RESUMO
The authors present a case of symptomatic non-sustained ventricular tachycardia induced by mechanical irritation of the outflow tract of the right ventricle by a loop in a permanent ventricular pacing lead. Reposition of the lead eliminated the rhythm disturbance.

The case of a patient with Prinzmetal's angina causing syncope due to atrioventricular block, and later causing death, is presented. Electrocardiogram during the episodes demonstrate multiple coronary artery involvement. Detection and differential diagnosis of ST-segment elevation during paced rhythm is discussed.

The case of a patient with a unipolar VVIR, who developed a sensor-driven increased pacing rate at rest following pulse generator replacement, is presented. The cause was pectoral muscle stimulation, which triggered a sensor-driven rate response in the supine position. The possible causes and management are discussed.
