Ventricular tachycardia (VT) is a series of three or more repetitive beats originating from the ventricle at a rate faster than the upper limit of normal for age. The QRS complex is ...

Q: Should siblings of patients with LQTS be evaluated?
A: Yes. Siblings and parents (even if asymptomatic) should have an ECG, Holter monitor, and exercise stress test for evaluation of the QT inte...

<bold>FIGURE 27-12</bold> Electrocardiographic (ECG) tracings of ventricular arrhythmias. Premature ventricular contractions (PVCs) (<italic>top tracing</bold>) originate from an ectopic focus in the ventricles, causing a distortion of the QRS complex. Because the ventricle usually cannot repolarize sufficiently to respond to the next impulse that arises in the sinoatrial node, a PVC frequently is followed by a compensatory pause. Ventricular tachycardia (<italic>middle tracing</bold>) is characterized by a rapi...

A 24-hour ambulatory electrocardiographic (ECG) recording in a patient with coronary artery disease and episodes of lightheadedness. A: At 10:28:36 p.m., the ECG records ST depression in leads aVF and V5, with ST elevation in lead V1. Over the next 4 minutes, the changes of acute injury progress. B: The rhythm degenerates into polymorphic ventricular tachycardia, from which the patient was resuscitated. This demonstrates the interaction of myocardial ischemia and subsequent ventricular arrh...
