Distinguishing the origin of ventricular tachycardia (VT) by electrocardiogram (ECG) which is performed in all patients, helps to diagnose the cause of VT before trying invasive procedures. The aim of this study was to compare the ECG findings in patients with VT originating from Right or Left ...
The ECG findings are wide QRS complexes because of aberrant conduction, heart rates greater than 100 bpm (usually 150–200 bpm), a regular rhythm and a constant QRS axis. Ventricular tachycardia can occur in a non-sustained manner, usually as short bursts of a few seconds that then ...
Ventricular Tachycardia (VT) ECG Review Ventricular tachycardia refers to a wide QRS complex heart rhythm — that is, a QRS duration beyond 120 milliseconds — originating in the ventricles at a rate of greater than 100 beats per minute. ...
IndicationsAny VT (ventricular tachycardia), including torsade de pointes (long QT syndrome). Digitalis induced VT. Ventricular fibrillation (VF). Mechanism of actionClass I-B antiarrhythmic. Receptor targetsINa ECG effectsQTc can slightly shorten ...
Ventriculartachycardiais the occurrence of three or more beats from a ventricularectopic pacemakerat a rate of more than 100 b.p.m. (Hillegass 2001). The ECG findings are wideQRS complexesbecause of aberrant conduction, heart rates greater than 100 b.p.m. (usually 150–200), a regula...

Of the post-infarction patients: 62 presented with ventricular tachycardia, 23 with ventricular fibrillation, while 44 had no clinically relevant arrhythmias. The ECG signals were recorded in three orthogonal X, Y, Z leads and averaged using cross-correlation method. Spectral analysis was performed ...
findings. Her preoperative investigations including ECG were all within normal limits. She was accepted for the proposed surgery. Aspirin was stopped 10 days prior to surgery and was replaced by paracetamol for pain relief. On the day of
There are many causes of ventricular tachycardia (Table 16.1). However, ventricular tachycardia usually occurs in patients with underlying structural heart disease. This can be acquired or inherited. Myocardial disease and scarring cause abnormal cardiac impulse formation and propagation, which can lead ...
Further analysis was aimed at assessing the course of the disease and the outcome of patients depending on the presumed origin of VT, as defined by the ECG morphology of the QRS complexes in the ECG during tachycardia: left bundle branch block (LBBB) morphology for right VT and right bundle...
