Supraventricular tachycardia that mimics ventricular tachycardia. 1977

S S Hamer, and L Lemberg

A short PR interval, a delta wave, and attacks of paroxysmal tachycardia are the principal features of the WPW syndrome. A grossly irregular rhythm with bizzare QRS complexes at rates exceeding 180 per minute is one of the paroxysmal tachycardias characteristic of the WPW syndrome. This arrhythmia deserves special attention, because it is often misinterpretated as ventricular tachycardia. The interpretation is atrial fibrillation with varying degrees of ventricular fusion and phasic ventricular aberration. Prompt electrical cardioversion is indicated because, at times, ventricular fibrillation may result. Quinidine sulfate used prophylactically because of its negative dromotropic effect on the accessory pathway promotes A-V transmission via the A-V node.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D003937	Diagnosis, Differential	Determination of which one of two or more diseases or conditions a patient is suffering from by systematically comparing and contrasting results of diagnostic measures.	Diagnoses, Differential,Differential Diagnoses,Differential Diagnosis
D004562	Electrocardiography	Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.	12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead

D013610	Tachycardia	Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.	Tachyarrhythmia,Tachyarrhythmias,Tachycardias
D014927	Wolff-Parkinson-White Syndrome	A form of ventricular pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave. In this syndrome, atrial impulses are abnormally conducted to the HEART VENTRICLES via an ACCESSORY CONDUCTING PATHWAY that is located between the wall of the right or left atria and the ventricles, also known as a BUNDLE OF KENT. The inherited form can be caused by mutation of PRKAG2 gene encoding a gamma-2 regulatory subunit of AMP-activated protein kinase.
