Short-Term Synchronization of an Intracardiac Leadless Pacemaker With a Transvenous Atrial Pacemaker in a Sedentary Patient.

We herein describe a case of successful atrioventricular synchrony at an 8-week follow-up in a patient who received a leadless pacemaker for recurrent right ventricular lead failures and had a pre-existing atrial transvenous pacemaker. Given the significant hemodynamic improvements, careful initial programming and adjustments during follow-up are needed.

Characteristics, management and outcome of patients with late-arrival STEMI in the Acute Coronary Syndrome Israeli Surveys (ACSIS).

Introduction: Patients with ST-elevation myocardial infarction (STEMI) and late arrival (>12 h) after symptom onset, are at high risk for mortality and heart failure and represent a challenge for management. We aimed to define patient characteristics, management, and outcome of late-arrival STEMI in Israel over the last 20 years.

Methods: We analyzed data of late-arrival STEMI (12-48 h and > 48 h) from the biennial acute coronary syndrome Israeli Surveys (ACSIS), as well as time-dependent changes [early (2000-2010) Vs.
