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.
A few decades ago all sudden cardiacarrests with documented ventricular fibrillation (VF) and structurally normal hearts were diagnosed as idiopathic ventricular fibrillation (IVF).
Arrhythmias (Irregular Heartbeats) Persistent abnormal heart rhythms can disrupt the heart’s pumping efficiency, eventually causing it to enlarge to maintain blood flow. Electrocardiogram (ECG/EKG) An ECG records the electrical activity of the heart and can help detect abnormalities in the heart’s rhythm that might contribute to enlargement.
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.
An electrocardiogram is a machine used to record the heart's electrical activity. Arrhythmia In simple words, arrhythmia refers to an irregular heartbeat. CardiacarrestCardiacarrest is a medical emergency in which the heart stops pumping blood to the body. ECG and EKG refer to the same thing.
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.
New insights into the use of the 12-lead electrocardiogram for diagnosing acute myocardial infarction in the emergency department. All electrocardiograms (ECGs) and coronary angiograms were blindly analyzed by experienced cardiologists. Harhash AA, Huang JJ, Reddy S, et al. aVR ST segment elevation: acute STEMI or not?
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.
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.
