2010年2月18日 · VPC couplet. Ventricular premature complexes (VPC) seen as wide bizarre QRS complexes not preceded by a P wave. Initial two VPCs are isolated while the last two occur in rapid sequence as a couplet. VPC couplets may be a forerunner of ventricular tachycardia. Isolated VPCs and the couplet are followed by a compensatory pause.

2020年7月21日 · 兩個VPC連在一起，稱為成雙之VPC (couplet VPC)。 非持續之VT，與成雙之VPC都不需要同步電擊治療。 如果病人情況不穩定，則給予靜脈注射Amiodarone 150 mg；如果穩定，給予口服Amiodarone即可。

2019年5月30日 · 但compensatory pauses仍有例外，比如：interpolated PVC (VPC出現在兩個sinus beats中間)。 APC及VPC原因 通常來自emotional stress、交感神經興奮(咖啡因攝取、beta-agonist)、毛地黃、電解質異常(低鉀、低鎂)或心肌缺血等。

2023年4月3日 · Ventricular premature complexes (VPCs), or premature ventricular complexes/contractions (PVCs), are ectopic beats that arise from within the ventricles. They are common and can occur in a wide variety of clinical scenarios and a diverse population. They can present in patients both with and without preexisting cardiac disease. [1] .

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.

2014年7月1日 · VPC Couplet. Monitor screenshot showing ventricular premature complexes in a couplet form (VPC couplet), with no preceding sinus beat in between.

Two consecutive premature ventricular contractions are referred to as a pair or couplet. If 3 to 30 premature ventricular contractions occur consecutively, it is referred to as non-sustained ventricular tachycardia (if the rate is >100 beats/min) or ventricular rhythm (if …

VPC 稱trigeminy,兩個VPC 連續稱couplet。心室期外收縮的原因可能心肌缺血、 電解質不平衡、菸酒咖啡因攝取過度等。但有許多時候�. 不出原因, 病人也不一定有症狀。一般健檢或是體檢的重�. 在於找出其中較具危險性�. 的QRS波落在前個心跳的T 波上. 免役體位, 其他VPC則為乙等體位。職業駕駛人換駕照所需體檢以及老人體檢篩檢出的病人,建議參�. 臨床症狀或理學檢查及抽血結果。若懷疑有結構性心臟病( s t r u c t u r a l h e a r t disease) 感神經亢奮時, 如焦慮、 緊�. …

首先，VPC耦合（couplet）是指連續出現的兩個VPC，這在某些情況下可能會引起擔憂，但在大多數健康個體中，偶爾出現的VPC耦合通常不會導致嚴重的心臟問題。

2024年10月8日 · Couplet — two consecutive PVCs; NSVT — between three and thirty consecutive PVCs (see below)
