Epicardial Pacemaker Lead-Induced Ventricular Tachycardia
2009年3月1日 · A 9-year-old boy with a permanent epicardial screw-type ventricular pacemaker lead (VVI mode), fitted due to a complete atrioventricular block after ventricular septal defect closure at 5 months of age, showed ventricular tachycardia during maximal exercise testing.
Ventricular tachycardia secondary to abandoned epicardial pacemaker lead
Epicardial device leads can cause ventricular arrhythmia without any obvious endocardial substrate abnormalities. Unusual provocation maneuvers should be considered outside of the standard ventricular pacing protocols, isoproterenol, and epinephrine. This should be guided by a careful history identifying unconventional triggers.
A case of cardiac tamponade due to coronary artery injury caused …
2020年10月13日 · We report a rare case of cardiac tamponade due to injury of the coronary artery by an atrial screw-in lead. A 74-year-old man visited the emergency room because of syncope. He was diagnosed with bradycardia tachycardia syndrome two years previously with presyncope. At that time, he took no drug that could cause bradycardia.
A rare case of epicardial left ventricular sutureless screw-in lead ...
2016年4月30日 · This case reviews a rare complication of an epicardial LV sutureless screw-in pacing lead, which was surgically placed and led to stenosis of the LAD artery. In circumstances of significant biventricular dilatation and axial rotation of the heart, the operator should be alerted to possible inferior and lateral displacement of the LAD artery.
Complete atrial screw lead penetration and ... - ScienceDirect
2024年9月23日 · Lead penetration caused an elevated threshold, resulting in a right pneumothorax, bloody pleural effusion, and pneumomediastinum. Thoracoscopic examination demonstrated that the lead body perforated from the right atrium and moved freely within the pericardial cavity.
Complete atrial screw lead penetration and contralateral …
2024年9月23日 · We report a case of atrial lead perforation that occurred one day after implantation. Lead penetration caused an elevated threshold, resulting in a right pneumothorax, bloody pleural effusion, and pneumomediastinum.
Results: Fifty-three atrial leads and 59 ventricular leads were implanted using active-fixation screw-in leads. The initial pacing threshold was slightly high, i.e., between 1.0 and 2.0 volts in...

Stress reduction on the lead body in the intracardiac and connector region due to the Helix Design of the wires. Protek shock-coil design for reduced tissue ingrowth and efficient energy delivery. Screw mechanism for active fixation. Bipolar sensing and pacing with 11 mm tip-to-ring distance.
A Review of Temporary Permanent Pacemakers and a Comparison …
Under fluoroscopic guidance, a pacemaker lead with a preformed stylet inside is advanced into the right ventricle and the screw is deployed either in the apex or the septum. Testing is done to ensure appropriate sensing, impedance, and capture thresholds.
