Long-term His-bundle pacing and cardiac function.
The article by Deshmukh et al 1 published elsewhere in the journal represents a tour de force for a number of reasons. The ability to chronically and selectively pace the His bundle not only represents an important methodological advance but also allows us to test the hypothesis that septal pacing in a fashion nearly identical to normal activation of the His-Purkinje system is superior to ventr...
متن کاملAutomatic External Cardiac Massage: a Portable Pneumatic External Cardiac Compression Machine.
Massage or manual compression of the heart is accepted as a useful procedure when heart action has ceased because of accident or temporarily disordered function. Experience in the operating theatre has shown that manual massage through the open chest should be maintained for over an hour before being abandoned, but the procedure is tiring, and the operator must be relieved at frequent intervals...
متن کاملHis bundle recordings in paroxysmal atrioventricular block produced by carotid sinus massage.
Electrograms from the bundle of His were recorded in two patients with acute myocardial infarction during paroxysmal atrioventricular block induced by carotid sinus massage. From the viewpoint of the surface electrocardiogram this arrhythmia was considered as a form of Type II (Mobitz) Ulo:k, the onset of which was related to a decrease in atrial rate. In the first patient, the conduction distu...
متن کاملThe physiology of external cardiac massage: high-impulse cardiopulmonary resuscitation.
In intact chronically instrumented dogs, left ventricular dynamics were studied during cardiopulmonary resuscitation (CPR). Electromagnetic flow probes measured cardiac output and coronary blood flow, ultrasonic transducers measured cardiac dimensions, and micromanometers measured left ventricular, right ventricular, aortic, and intrathoracic pressures. The dogs were anesthetized with morphine,...
متن کاملRight atrial laceration. Complication of external cardiac massage.
Right atrial laceration is described as a complication of external cardiac massage in two patients. In each there was a pre-existent cause of weakness of the atrial wall. There was pronounced right atrial dilation with attenuation of the wall in one case, and in the other there was a granulomatous myocarditis involving the atrial wall. The significance of atrial laceration as a complication of ...
