Ventricular pacing: to pace or not to pace

Pacing from the right ventricular apex has been the clinical standard for decades but has recently come into question with a growing trend towards reducing ventricular pacing as much as possible. The earliest devices provided asynchronous ventricular pacing in patients whose indication for pacing was asystolic complete heart block. RV apical pacing was literally the difference between life and ...

To Pace Or Not To Pace! — Prevention Of Atrial Fibrillation After Coronary Artery Bypass Surgery

Atrial fibrillation (AF) is a very undesirable, but unfortunately a common arrhythmia following coronary artery bypass graft (CABG) surgery, occurring in up to 40% of patients1. There is an increase in hospital stay2 and adds to the overall cost of the surgery. Atrial fibrillation occurrence may identify a subset of patients with reduced survival3. Prevention of AF therefore would have a signif...

acing the right ventricle : To pace or not to pace ? nne

r i u s P o y s A number of important clinical trials have recently reorted on clinical outcomes associated with different cariac pacing modalities. As a consequence of these pubications, concerns about the possible deleterious effects of ight ventricular (RV) apical pacing, even in an atriovenricular (AV) synchronous mode, have arisen. There have ven been calls to consider left ventricular (LV...

Why do quadrupeds exhibit exclusively either trot or pace gaits?

Quadrupeds exhibit versatile gait patterns (walk, trot, pace, bound, etc.), in response to the locomotion speed and environmental conditions [1]. Furthermore, in the middle speed locomotion, quadrupeds exhibit “exclusively” either trot or pace gaits; horses exhibit a tort gait, whereas camels exhibit a pace gait. These locomotor patterns are generated via the coordination of limb movements, i.e...
