He developed cardiac arrest shortly after the ECG in Figure-1 was recorded. What is the most likely cause of this arrhythmia? IMPRESSION: Given the presence of a wide tachycardia — with 2 distinct QRS morphologies, and no sign of P waves — a presumed diagnosis of B i D irectional Ventricular Tachycardia has to be made.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by fibrofatty replacement of the ventricular myocardium due to specific mutations, leading to ventricular arrhythmias and sudden cardiac death. channels, Connexin 43 and Wnt signalling, potentially modifying myocardial fibrosis.

Chagas disease (ChD) was associated with increased rates of ventricular tachycardia and ventricular fibrillation in ICD patients only in the initial two periods, but there was no statistical difference in the last period. Time periods were chosen based on the establishment of the Arrhythmia Service in 2011.

Clinical contexts leading to diagnosis were SCD in 3 (6%), ventricular arrhythmias in 15 (29%), chest pain in 8 (15%), heart failure in 6 (12%) and familial screening in 20 (38%). Significant right ventricular involvement was an exclusion criterion. Results Fifty-two patients (63% males, age 45 years (31–53)) composed the study cohort.

Brugada syndrome is thought to account for about one fourth of sudden cardiac deaths in individuals with structurally normal heart. This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. I am always happy to see this ECG of Brugada syndrome as it was sent to me by Prof.

ICDs are safe and effective for terminating life-threatening ventricular arrhythmias; transvenous leads, which run through the veins and into the heart, can result in complications. It works by briefly delivering pacing pulses to the heart at a rate faster than the tachycardia.

It can automatically detect life threatening ventricular arrhythmias and treat them, either with a shock or, sometimes by overdrive pacing. You may be knowing that one of the causes for inappropriate ICD shocks, is supraventricular arrhythmia, wrongly detected by the defibrillator as a ventricular arrhythmia and giving a shock.

There are a number of things to look for in an ECG that can hint at arrhythmia as the cause of an apparent seizure. There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). Below are some of the conditions to be aware of: Preexcitation Brugada syndrome.
