Supraventricular Ectopic Beat (SVE) A beat that is premature, narrow in width but may be slightly different shaped than the patient’s “normal” beats. These beats may be sinus, atrial, or nodal in origin.

ECG shows regular, normal-appearing QRS complexes without identifiable P waves or with retrograde P waves (inverted in the inferior leads) that occur shortly before (< 0.1 second) or after the QRS complex. The rhythm is distinguished from paroxysmal supraventricular tachycardia by the lower heart rate and gradual onset and offset.

2009年9月15日 · Couplets indicate a higher potential for arrhythmia than isolated ventricular ectopic beats. If three ventricular ectopic beats occur in a sequence at a rate above 100 per minute is called a salvo or a short run of nonsustained ventricular tachycardia.

Kardia Advanced Determination “Sinus with Supraventricular Ectopy (SVE)” indicates sinus rhythm with occasional irregular beats originating from the top of the heart. A common reason for this is premature atrial contractions (PACs).

2009年7月9日 · Ventricular ectopic beats are the most common cardiac electrical abnormality for which cardiologist’s consultation is sought.VPDs are one of most benign observations in ECG and and almost every heart experiences it. In 24 hour holter recordings it was reported up to 25% of healthy individuals .

Supraventricular tachycardia (SVT) can be recognized on the ECG by a narrow QRS tachycardia with either absent P waves or P waves which are distinctly different from those in sinus rhythm.

2013年4月30日 · Supraventricular ectopics are abnormal heart beats with trigger signals originating above ventricles, the lower chambers of the heart. They could be from the atrium or atrioventricular junction. Isolated supraventricular ectopics may not need any specific treatment other than that of the disorder causing them.

Multiformed PVCs are common in digitalis intoxication. PVCs may occur as isolated single events or as couplets, triplets, and salvos (4-6 PVCs in a row), also called brief ventricular tachycardias.

2011年8月23日 · ACC/AHA/ESC guidelines for the management of patients with supraventricular arrhythmias--executive summary. a report of the American college of cardiology/American heart association task force on practice guidelines and the European society of cardiology committee for practice guidelines (writing committee to develop guidelines for the managemen...

Excessive supraventricular ectopic activity was associated with significantly increased risk (>60%) of mortality and stroke. A 2.7 fold increase in rate of AF was also observed during follow up. A stepwise increase in the risk of the primary endpoint by 27% and risk of AF by 50% was noted for each increase of 10 SVEC per hour.
