AI Article Synopsis

  • Electrocardiography is a crucial and fast tool for identifying patients with acute coronary syndromes, especially those needing emergency reperfusion therapy.
  • Identifying conditions like bundle branch blocks complicates diagnosis; ST elevation can be recognized in RBBB, but LBBB requires specific criteria (Sgarbossa and Barcelona).
  • A case study highlights a patient with STEMI and TAVB who showed RBBB, then shifted to LBBB but improved to sinus rhythm after reperfusion therapy, highlighting the need for prompt treatment including temporary pacing.

Article Abstract

Electrocardiography is the fastest bedside tool for rapidly identifying patients with acute coronary syndromes who require emergency reperfusion therapy. Some of the circumstances that make identification more complex are bundle branch block patterns. ST elevation in the right bundle branch block (RBBB) can still be detected, but the left bundle branch block (LBBB) must use specific criteria such as Sgarbossa and Barcelona. We present a patient with anteroseptal ST-segment elevation (STEMI), total AV block (TAVB) with ventricular escape rhythm RBBB pattern, and then turned into a LBBB pattern. Fortunately, it immediately turned into sinus rhythm after reperfusion therapy. It is essential to be able to identify STEMI in patients with BBB patterns. In addition, to provide the best possible outcomes for the patient, we must understand that the best way to manage STEMI with TAVB is to immediately install a temporary pacemaker and initiate reperfusion therapy.

Patients presenting with suspected acute coronary syndrome (ACS) in the emergency department (ED) require rapid and accurate electrocardiographic (ECG) evaluation. This study aims to assess conventional ECG markers for diagnosing non-ST-elevation ACS (NSTE-ACS) in patients with chest discomfort and right bundle branch block (RBBB). A nested case-control design was employed to compare patients with RBBB admitted to the ED for suspected cardiac ischemia, focusing on those who developed NSTE-ACS versus those who did not.

Transthyretin Cardiac amyloidosis (ATTR-CA) is an increasingly recognised cause of heart failure in our elderly patients with preserved ejection fraction. Patients with ATTR-CA who require permanent pacemaker implantation often have preserved ejection fraction and do not meet the clinical indication for cardiac resynchronization therapy (CRT). In these patients, left bundle branch area pacing (LBBAP) can be a reasonable option to maximise physiological activation of the left ventricle.

Background: Non-response to cardiac resynchronization therapy (CRT) is an important issue in the treatment of heart failure with reduced ejection fraction (HFrEF) and non-left bundle branch block (LBBB). Electrocardiogram-gated myocardial perfusion single-photon emission computed tomography imaging (G-MPI SPECT) is typically used to assess left ventricular (LV) dyssynchrony. This study aimed to determine whether G-MPI parameters are associated with non-responsiveness to CRT.

Left bundle branch pacing (LBBP) is an emerging physiological pacing technique characterized by stable pacing parameters and a narrower QRS duration. This study aims to compare the long-term efficacy and safety of biventricular pacing (BIVP) and LBBP in patients with heart failure with reduced ejection fraction (HFrEF) and complete left bundle branch block (CLBBB). A retrospective analysis was conducted on 35 patients with chronic HFrEF accompanied by CLBBB treated at our center from April 2018 to October 2022.

Background: Left bundle branch block (LBBB) is a rare conduction disorder in athletes associated with ventricular dyssynchrony, which can lead to left ventricular systolic dysfunction and exercise intolerance. Inappropriate sinus tachycardia (IST) is characterized by an excessive heart rate (HR) that is not related to physiological needs, often resulting in reduced exercise capacity. Managing these conditions in athletes can be challenging, as standard treatments like beta-blockers and ivabradine, while effective in controlling HR, are described to be associated with a reduction in maximal exercise performance.
