WebPVCs are also common in the intensive care setting. Like PACs, they are generally caused by abnormal automaticity or triggered activity. PVCs can occur in the setting of metabolic derangement, hypoxia, strain, as a result of medications, as a response to catecholamines, or by direct stimulation due to a catheter or a device touching the myocardium. WebMuch of the reduced contractility can be accounted for by the severity of the acidosis. Although a mild acidosis can delay or prevent damage to the myocardium from ischaemia or hypoxia, a severe acidosis is not beneficial and may even cause tissue necrosis. Publication types Review ...
