Delayed perforation of the right ventricle by pacemaker/automated implantable cardioverter-defibrillator lead: A single-center experience

Heart India, 2021
Introduction: Cardiac perforation by pacemaker/automatic implantable cardioverter-defibrillator (AICD) lead can be a life-threatening emergency. Delayed cardiac perforation by pacemaker/AICD lead is defined as perforation occurring after a period of 1 ...

Tbx18 and the generation of a biological pacemaker. Are we there yet? [PDF]

, 2016
A group of approximately 10,000 cells in the sinoatrial node (SAN), which is located at the entry of the right superior caval vein into the right atrium, is responsible for regular heart beating under different physiological conditions [1]. While the SAN

Correlation of aortic valve annular plane assessment by on‐table three‐dimensional rotational angiography and preprocedural computed tomography

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1316-1322, December 1, 2022., 2022
Abstract Objectives To assess the correlation between the aortic valve annular plane (AVAP) obtained by preprocedural computed tomography (CT) with on‐table three‐dimensional rotational angiography (3DRA), in patients undergoing transcatheter aortic valve replacement (TAVR).

Subacute Right Ventricle Perforation by Pacemaker Lead Presenting with Left Hemothorax and Shock

Case Reports in Cardiology, 2015
Cardiac perforation by pacemaker is a rare but potentially fatal complication. Acute perforations occurring within twenty-four hours of insertion of pacemaker can lead to hemopericardium, cardiac tamponade, and death.

Leadless pacemaker – A savior in crisis

Journal of the Practice of Cardiovascular Sciences, 2023
The current case describes the successful implantation of a leadless pacemaker in an elderly patient with multiple complexities. The patient had an in situ cardiac pacemaker with a suspected displaced right ventricular lead and was stabilized using ...

Complete atrial-specific knockout of sodium-calcium exchange eliminates sinoatrial node pacemaker activity. [PDF]

, 2013
The origin of sinoatrial node (SAN) pacemaker activity in the heart is controversial. The leading candidates are diastolic depolarization by "funny" current (If) through HCN4 channels (the "Membrane Clock" hypothesis), depolarization by cardiac Na-Ca ...

Direct Powering a Real Cardiac Pacemaker by Natural Energy of a Heartbeat.

ACS Nano, 2019
Implantable medical devices are widely used for monitoring and treatment of severe diseases. In particular, an implantable cardiac pacemaker is the most effective therapeutic device for treating bradyrhythmia, however its surgical replacement is ...

QT and Tpeak‐Tend interval variability: Predictive electrical markers of hospital stay length and mortality in acute decompensated heart failure. Preliminary data

Clinical Cardiology, Volume 45, Issue 12, Page 1192-1198, December 2022., 2022
Abstract Background As previously reported, an increased repolarization temporal imbalance induces a higher risk of total/cardiovascular mortality. Hypothesis The aim of this study was to assess if the electrocardiographic short period markers of repolarization temporal dispersion could be predictive of the hospital stay length and mortality in ...

Successful conversion of complete atrioventricular block to sinus rhythm without cardiac pacemaker: A case report

JKKI (Jurnal Kedokteran dan Kesehatan Indonesia), 2019
Complete atrioventricular (AV) block is a medical emergency, which is related to cardiac arrest if left untreated. The insertion of permanent cardiac pacemaker is strongly indicated for its treatment.

Electrical interventricular delay and left ventricular delay in right ventricular pacemaker pacing before upgrading to cardiac resynchronization therapy

Current Directions in Biomedical Engineering, 2017
Cardiac resynchronization therapy with biventricular pacing is an established therapy for heart failure patients with sinus rhythm, reduced left ventricular ejection fraction and electrical ventricular desynchronization.
