2012 Arrhythmia Tachycardia 
All About Cardiovascular System and Disorders

In that study commonest ECG abnormalites were QTc prolongation followed by brady/tachycardia and then ST segment deviations [3]. Cerebrovascular damage can cause cardiac arrhythmias related to disinhibition of right insular cortex with resulting increased sympathetic tone. 2012 Dec;7(4):290-4. 2012 Dec;7(4):290-4.

This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? Troponins 34>33>43, likely secondary to myocardial injury from tachycardia. Sinus tachycardia does not go this fast. A 60-something ow healthy male had syncope while on treadmill. What do you want to do?

This familial cardiac arrhythmia is the result of gene mutation. These patients are at high risk for malignant arrhythmias. Typically — these arrhythmias are induced by exercise or intense emotional states ( ie, associated with increased catecholamine discharge ). The heart is structurally normal in patients with CPVT.

What is unusual about this arrhythmia? Doing so suggests that the R-R interval of this exceedingly rapid arrhythmia is just a tiny amount over 1 large box — which corresponds to a ventricular rate just under 300/minute ( ie, between 290-300/minute ). How would YOU interpret the ECG in Figure-1 ?

She was awake, alert, well perfused, with normal mental status and overall unremarkable physical exam except for a regular tachycardia, possible rales at both bases, some mild RUQ abdominal tenderness. Thus, I believe it is a regular, monomorphic, wide complex tachycardia. Or it could simply still be classic VT. What is the Diagnosis?

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.

Methods Patients were retrospectively evaluated between January 2012 and June 2020. 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.
