Although premature ventricular beats (PVBs) in young people and athletes are usually benign, they may rarely mark underlying heart disease and risk of sudden cardiac death during sport. This review ...

This ECG shows ventricular fibrillation. Disorganized wide QRS complexes of relatively low amiplitude are present at a rate of greater than 300 beats per minute. Note the sharp spikes intermittently ...

Genetic mutations can impact the heart’s structure or electrical functions, potentially leading to inherited arrhythmias. Several types of heart arrhythmias, including atrial fibrillation, Brugada ...

Monomorphic ventricular tachycardia is an irregular heartbeat where the bottom chambers of your heart beat quicker than usual. It can cause symptoms such as shortness of breath, dizziness, or fatigue.
