The targeted Automated External Defibrillator (AED) program in the Sao Paulo Metro has yielded promising results in improving survival rates for individuals experiencing out-of-hospital cardiacarrest (OHCA) due to ventricular arrhythmias. Circulation, Volume 150, Issue Suppl_1 , Page ASu505-ASu505, November 12, 2024.
He was defibrillated into VT. He then underwent dual sequential defibrillation into asystole. But cardiacarrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. After cardiacarrest, I ALWAYS wait 15 minutes after an ECG like this and record another. They started CPR.
While on telemetry monitoring he suffered cardiacarrest and was resuscitated. What ECG finding may have contributed to (or precipitated) the cardiacarrest? After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation.
Automated external defibrillators (AEDs) and implantable cardioverter defibrillators (ICDs) are used to treat life-threatening arrhythmias. AEDs and ICDs use shock advice algorithms to classify ECG tracings as shockable or non-shockable rhythms in clinical practice.
A 60-something woman presented after a witnessed cardiacarrest. She was never defibrillated. This is commonly found after epinephrine for cardiacarrest, but could have been pre-existing and a possible contributing factor to cardiacarrest. Cardiac cath showed minimal disease. She recovered.
If VT is not treated, it can lead to cardiacarrest, which is when the heart stops beating. In fact, VT is the most common cause of sudden cardiacarrest. Patients may feel a fluttering in the chest, chest pain, shortness of breath and dizziness or lightheadedness as a result. Q: How is VT typically treated?
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:There is no specific treatment for sudden cardiacarrest (SCA) manifesting as pulseless electric activity (PEA) and survival rates are low; unlike ventricular fibrillation (VF), which is treatable by defibrillation.
See this post: How a pause can cause cardiacarrest 2. Because she has cardiomyopathy and ventricular dysrhythmias, the pacer included an Implanted Cardioverter-Defibrillator (ICD) Echo 6 days later after CRT: Normal estimated left ventricular ejection fraction. The plan: 1. Place temporary pacemaker 3.
Rarely, implantation of cardiac implantable electronic devices (CIEDs) becomes necessary.1 1 A rare but significant issue in post-OHT patients is ventricular arrhythmias, in extreme cases leading to cardiacarrest and implantation of an implantable cardioverter-defibrillator (ICD) for secondary prevention.
Edited by Bracey, Meyers, Grauer, and Smith A 50-something-year-old female with a history of an unknown personality disorder and alcohol use disorder arrived via EMS following cardiacarrest with return of spontaneous circulation. She was successfully revived after several rounds of ACLS including defibrillation and amiodarone.
Smith’s ECG Blog: SQTS is an inherited cardiac channelopathy determined by the presence of symptoms ( syncope, cardiacarrest ) — positive family history — and the ECG finding of an abnormally short QTc interval. Treatment is by ICD ( implantable cardioverter defibrillator ).
AI recognizing cardiacarrests in emergency calls. Recently, hospitals have failed to identify 25% of cases of cardiacarrest. Alternatively, it also helps enhance arrhythmia management with coronary artery disease. Along with it, a guideline-based algorithm helps identify implantable cardioverter defibrillators.
She underwent cardiopulmonary resuscitation for VT/VFib — with ROSC ( R eturn O f S pontaneous C irculation ) following defibrillation and treatment with Epinephrine and Amiodarone. A series of cardiacarrhythmias were seen during the course of her resuscitation — including the interesting arrhythmia shown in the long lead II of Figure-1.
IV administration of potassium is indicated when arrhythmias are present or hypokalemia is severe (potassium level of less than 2.5 If cardiacarrest from hypokalemia is imminent (i.e., malignant ventricular arrhythmias are present), rapid replacement of potassium is required. How would you treat? mEq/L, from 1.9
When discussing heart health, heart attacks and cardiacarrest are two terms that are often mistaken for one another. Understanding the difference between heart attack and cardiacarrest can help in recognizing symptoms, seeking prompt medical care, and even saving lives. What is CardiacArrest?
Case submitted by Magnus Nossen MD from Norway, written by Pendell Meyers A man in his 50s with no pertinent medical history suffered a witnessed cardiacarrest. 12 minutes later, the patient went back into VFib arrest and underwent another 15 minutes of resuscitation followed by successful defibrillation and sustained ROSC.
Photo by Cedars-Sinai milla1cf Fri, 03/01/2024 - 08:25 March 1, 2024 — Two new studies by Cedars-Sinai investigators support using artificial intelligence (AI) to predict sudden cardiacarrest-a health emergency that in 90% of cases leads to death within minutes.
Chugh’s leadership in arrhythmia research and care is extraordinary,” said Eduardo Marbán, MD, PhD , executive director of the Smidt Heart Institute. Although “sudden cardiacarrest” and “heart attack” are often mistaken to be the same, the conditions are quite different.
He developed cardiacarrest shortly after the ECG in Figure-1 was recorded. What is the most likely cause of this arrhythmia? C ASE C onclusion: As noted above — today's patient developed cardiacarrest shortly after arrival in the ED. QUESTIONS: How would YOU interpret the ECG in Figure-1 ?
Arrhythmias (Irregular Heartbeats) Persistent abnormal heart rhythms can disrupt the heart’s pumping efficiency, eventually causing it to enlarge to maintain blood flow. Implantable Cardioverter-Defibrillator (ICD) to help manage dangerous heart rhythms.
However, he suddenly developed a series of malignant ventricular arrhythmias. He required multiple defibrillations within a period of a few hours. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.
Sudden cardiac death is one of the main causes of mortality in patients with known or occult cardiac disease and is potentially preventable by early resuscitation. 1 Underuse of AEDs is a multifaceted problem with the number of available devices in a given distance to a person with out-of-hospital cardiacarrest (OHCA).
At cath, he immediately had incessant Torsades de Pointes requiring defibrillation 7 times and requiring placement of a transvenous pacer for overdrive pacing at a rate of 80. IV administration of potassium is indicated when arrhythmias are present or hypokalemia is severe (potassium level of less than 2.5 mEq/L, from 1.9
During the intravenous lacosamide infusion, the patient developed sudden cardiacarrest caused by ventricular arrhythmias necessitating resuscitation. Of note, the patient had a family history of sudden cardiac death. 2893C>T, p.Arg965Cys) in the SCN5A gene.
The arrhythmia spontaneously converted before defibrillation was achieved. This patient is actively dying from a left main coronary artery OMI and cardiacarrest from VT/VF or PEA is imminent! Complete LMCA occlusion is associated with clinical shock and/or cardiacarrest.
Introduction Sudden cardiacarrest is a major cause of morbidity and mortality worldwide and remains a major public health problem for which better non-invasive prediction tools are needed. Primary preventive therapies, such as implantable cardioverter defibrillators, are not personalized and not predictive.
The patient was put on Extracorporeal Life Support in the ED 3 hours after initial resuscitation, the core temp was 30° C and the patient was defibrillated with a single attempt. Perhaps the bifascicular block ( RBBB/LPHB ) present on ECG #1 — but which resolved by ECG #2 — was also ischemic-related from the cardiacarrest.
Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
This ECG pattern may be diagnostic of B rugada S yndrome IF seen in association with: i ) a history of cardiacarrest; polymorphic VT; or of non-vagal syncope; and / or ii ) a positive family history of sudden death at an early age; and / or iii ) a similar ECG in relatives. Cardioversion/defibrillation. Acute febrile illness.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Sudden cardiac death is the most common cause of death in childhood hypertrophic cardiomyopathy (HCM). Recently, 2 risk scores have been developed to estimate the 5-year risk of sudden cardiac death. males), with a mean follow-up of 8.65.5
This causes deadly arrhythmias and should be considered in patients with syncope and short QT 2. Smith’s ECG Blog: SQTS is an inherited cardiac channelopathy determined by the presence of symptoms ( syncope, cardiacarrest ) — positive family history — and the ECG finding of an abnormally short QTc interval.
Further history later: This patient personally has no further high risk features (syncope / presyncope), but her mother had sudden cardiacarrest in sleep. Conclusion of this paper: Fever is a great risk factor for arrhythmia events in Brugada Syndrome patients. We repeated the ECG: Brugada pattern is mostly resolved.
We rapidly defibrillated her, and with return of normal sinus rhythm. Several minutes later the patient developed V-fib again > 200J defibrillation with return to NSR. Rapid sequence intubation was performed for airway protection in setting of recurrent V-fib and defibrillations. Chest X-ray also showed pulmonary edema.
