By 1909 ECGs were being used to diagnose cases of arrhythmia; by 1910 to diagnose indicators of a heart attack. In April 2022 BMS had received FDA approval for Camzyos, the first drug developed specifically for targeting HCM. For example, in March 2023 Bristol Myers Squibb (BMS) partnered with Viz.ai How Has Funding Progressed?

This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. Opinion is divided on the need for electrophysiology study. With proper precautions, risk can be reduced.

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.

Methods and Results Patients with symptomatic, drug-resistant paroxysmal AF for first ablation were prospectively enrolled from September 2020 to January 2022. First-pass isolation, acute pulmonary vein (PV) reconnections, 1-year arrhythmia recurrence, and major complications were assessed. vs. 53.3%, p  = .005). vs. 14.2%, p  = .246).

We aimed to investigate the prevalence of NSVT in patients with ATTRwr-CA, and the association of NSVT with sustained ventricular arrhythmias (VA) and all-cause mortality. Patients with NSVT have a higher risk of incident sustained VT compared to those without NSVT.

A subgroup of patients with MVP may experience ventricular arrhythmias and sudden cardiac death (“arrhythmic mitral valve prolapse” [AMVP]) but how to stratify arrhythmic risk is still unclear. Abstract Introduction Mitral valve prolapse (MVP) is a common clinical condition in the general population.

Outcome Electrophysiologic study showed an accessory pathway (WPW, antidromic AVRT) Why did adenosine not work? PEARL #1 : Getting an Echo when your arrhythmia patient is stable can sometimes prove highly insightful for determining the rhythm. 6 mg often does not work, but especially in low flow states.

Patient was referred to electrophysiologic testing due to suspicion of afib and WPW. During electrophysiologic testing AVRT was induced, which degenerated to afib with ortho and antidromic conduction. What I found especially interesting about this arrhythmia — is the variation in QRS morphology throughout.

Distinction is made between: ERP ( E arly R epolarization " P attern" ) in which the ECG findings of early repolarization are seen in the absence of symptomatic arrhythmias. ER associated with a rapidly ascending ( upsloping ) ST segments are the most common form and are also generally associated with low risk of malignant arrhythmias.

So, we are looking for signs of an underlying regular atrial rhythm ( with perhaps slight sinus arrhythmia ) — and it is much easier to find this when you know what you are looking for!

He was discharged with an event monitor and electrophysiology follow up. He subsequently woke up on the ground, unsure how long he had been unconscious. He presented for evaluation where inpatient workup including monitoring on telemetry was unremarkable. What do you think? Figure-1: I've labeled today's continuous rhythm strip.
