If necessary, direct antiarrhythmic therapy, including antiarrhythmic. Nevertheless, ventricular tachyarrhythmias are better treated with devices that can cardiovert and defibrillate as well as pace ( implantable cardioverter-defibrillators Implantable Cardioverter-Defibrillators (ICD) The need for treatment of arrhythmias depends on the symptoms and the seriousness of the arrhythmia. In these cases, a paced beat will be seen after a pause that is equal to this lower predetermined heart rate. However, there may be intermittent capture when the atrial pacemaker is in a demand mode and is activated only when the intrinsic atrial rate falls below a preset level. Some tachyarrhythmias may be terminated by overdrive pacing with a brief period of pacing at a faster rate the pacemaker is then slowed to the desired rate. There is 100 percent capture if the rhythm is entirely paced. On the electrocardiogram or rhythm strip, a pacing spike can be seen with no P or QRS complex subsequently following the pacing spike. The most common cause is idiopathic fibrosis and sclerosis of the conduction. Loss of capture, also known as noncapture, is when the myocardium does not respond to the electrical stimuli from the pacemaker or ICD. read more or high-grade atrioventricular block Atrioventricular Block Atrioventricular (AV) block is partial or complete interruption of impulse transmission from the atria to the ventricles.
