These findings suggest that the sensitivity of relaxation to the loading conditions might be determined by both the activation decay rate and the cross bridge kinetics. 展开 关键词: relaxation activation decay atrium ventricle DOI: 10.1007/BF01907435 被引量: 13 ...
Atrial fibrillation may automatically revert to normal sinus rhythm and require no treatment, in a few people. Many people with AFib can be treated with heart rate controlling or rhythm-controlling medications (see prevention). Moreover, some people with AFib may respond well to electrical cardiover...
Quantitative assessment of right atrial function by strain and strain rate imaging in patients with heart failure. We sought to evaluate the regional longitudinal strain/strain rate profiles in the right atrial wall to quantify right atrial function in systolic heart fa... Zahra,Ojaghi,Haghighi,....
Heart rate : Atrial rate > 300/min Some beats are irregularly modulated by the atrioventricular (AV) node Ventricular rate = 90–170/min Effects: Atrial remodeling: irregular impulses and contractions lead to progressive dilation and fibrosis of the atria → higher risk for AF → vicious cycl...

These beats are too weak to push enough blood out of the heart to your lungs and body. What Does AFib With RVR Feel Like? A normal heartbeat is 60 to 100 beats per minute (BPM). In AFib with RVR, your heart rate can reach more than 100 BPM. What Are the Risk Factors for AFib...
On Day 6 after admission, at 9:53 a.m. The patient developed atrial fibrillation again. A few minutes later, the heart rate rose to 153 bpm, triggering atrial fibrillation with high ventricular rate alarm, and the doctor continued amiodarone for cardioversion retreatment....
前者稱為心律控制(rhythm control),後者稱為心速控制(rate control)。心律控制的理想是利用壓抑AF,使病人不致於產生上述所提因AF而引起的併發症,特別是中風及心力衰竭,並且維持正常的心房及心室配合(synchronization)的功能,以達到最好的心排出量(cardiac output)。而心速控制,雖不能壓抑AF,但可讓心室的心跳維持...
