Congenital Long QT Syndrome (LQTS) can result in fatal cardiac arrhythmias. The main pharmacological treatment includes beta-blockers; however, while effective at reducing cardiac events, beta-blockers do not treat underlying mechanisms of the disease, and patients occasionally experience breakthrough cardiac events or side effects.

Abstract Introduction Premature ventricular complexes (PVCs) are the most common ventricular arrhythmia that are encountered in the clinical practice. Both antiarrhythmic drugs (AADs) and catheter ablation (CA) are recognized treatment modalities for any cardiac arrhythmias.

In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished. We discussed several pharmacologic and electrical options. 2) Tachycardia to this degree can cause ST segment changes in several ways.

The key risk factor for cardioembolic stroke is atrial fibrillation or flutter, and oral anticoagulation (OAC) is recommended in all but the lowest-risk patients with evidence of these arrhythmias. Overall, comprehensive assessment and pharmacological modification of risk factors are central to stroke prevention.

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 ?

Atrial fibrillation (AF) is the most common arrhythmia in humans. It affects 5% of the population over the age of 65 years and is projected to rise as the population ages. Experimental data from animal models of AF shows that AF is associated with progressive structural and electrical remodeling of the atria.
