Inappropriate ICD shocks are associated with increased mortality. They also impair patients' quality of life, increase hospitalizations, and raise health-care costs. Nearly 80% of inappropriate ICD shocks are caused by supraventricular tachycardia. Here we report the case of a patient who received a single-lead dual-chamber sensing ICD for primary prevention of sudden cardiac death and experien...

The authors would like to thank Professor Halil Dogan (Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkey) for informing them of the following error. The following sentence within the last paragraph of the ‘Diltiazem and Atrial Arrhythmias’ section, ‘‘A retrospective study evaluated 77 patients with supraventricular tachycardia treated with oral adenosine or intravenous di...

UNLABELLED A young man underwent 2 catheter ablation procedures because of frequent episodes of paroxysmal supraventricular tachycardia (SVT). A left accessory pathway was ablated in the first procedure. The patient underwent the second ablation procedure due to a recurrent SVT demonstrated by 12-lead electrocardiogram two weeks after the first procedure. During the second procedure, a SVT with...

A 29-year-old woman underwent an electrophysiologic procedure because of a 10-year history of recurrent episodes of paroxysmal supraventricular tachycardia. The baseline cycle length, atrial-His (AH), and His-ventricular (HV) intervals were 550, 50, and 45 msec, respectively. The AV block cycle length was 270 msec. With programmed atrial stimulation, there was no evidence of dual AV nodal pathw...

A patient who had disabling supraventricular tachycardia showed electrophysiologic evidence of coexistent right and left Kent bundles. The supraventricular tachycardia was accelerated by sequential antegrade and retrograde conduction over the right and left Kent bundles, respectively. Spontaneous blocking of the conduction through the right Kent bundle was associated with a slowing of the tachy...

having a broad QRS complex, it is important to be able to diVerentiate between a supraventricular and a ventricular tachycardia. Medication given for the treatment of a supraventricular tachycardia (SVT) may be harmful to a patient with a ventricular tachycardia (VT). 2 A reasonable haemodynamic condition during a tachycardia may erroneously lead to the wrong diagnosis of SVT. Familiarity with ...
