Pacemaker complicationscan be categorized as failure to pace, failure to capture, failure to sense, and inappropriate rate (tachyarrhythmias). Failure to sense is the most common cause ofpacemakermalfunction. Failure to pace is usually due to oversensing. Magnet application converts the pacemaker to...
An immediate electrocardiogram showed complete heart block with pacemaker spikes and failure to capture. Chest X-ray showed coiled and retracted right ventricular lead and rotated pulse generator. An emergent temporary pace maker was set at a rate of 60 beats per minute. Subsequently, she underwent...
Treatment, prevention, and termination of pacemaker-mediated tachycardia (PMT) typically involves altering the pacemaker programming to prevent sensing of the retrograde atrial electrogram. This is most easily done by prolonging the postventricular atrial refractory period (PVARP). During the PVARP, the...
Failure to capture (despite pacer spike) Pacemaker spike present without ensuing QRS Complex May indicate lead Fracture or dislodgement, or malfunction central to the device Lead displacement is the most common cause and typically occurs in first month Other causes include cardiac ischemia or infarctio...
Complications in cat 2 included failure of pacemaker capture, endocardial lead dislodgement, and pulse generator pocket seroma. Cats with symptomatic bradycardia caused by second-degree and third-degree AV block can be effectively treated by pacemaker implantation by surgical endomyocardial or perivenous...
Emergency department (ED) treatment of capture failure depends on the clinical scenario. If use of a magnet does not generate a pacing rhythm with myocardial activity and palpable pulses, a number of possibilities must be considered. If pacer spikes appear on the monitor without capture, then ...
Standard heart failure therapy is warranted for patients with LV dysfunction. Differential Diagnosis Tachyarrhythmias, most commonly atrial fibrillation or flutter, are the usual differential and can be easily excluded by an ECG and device interrogation. LV dysfunction and cardiomyopathies which usually ...
Although complicated with heart failure and fever, it could not fully explain the QT interval prolongation. Complete atrioventricular block was the main cause of prolongation of QT interval [8].When associated with premature ventricular contractions, it was very easy to induce TdP. However, the ...
failure or left bundle branch block who require biventricular pacing. The third wire passes through the coronary sinus and into a coronary vein to simulate the left ventricle transvenously. This configuration is commonly referred to asCardiac Resynchronization Therapy (CRT). Rarely additional leads ...
