Dyssynchrony without dysfunction: Left bundle branch block does not acutely reduce cardiac output

The Journal of Physiology, EarlyView.
Abstract figure legend Six electromechanical in silico heart models were simulated under healthy and pure acute left bundle branch block (LBBB) conditions. LBBB induced electrical dyssynchrony and increased left ventricular free wall strain, while the right and left ventricular ejection fraction remained relatively unchanged.

Acute Isolation of Cells from Murine Sino-atrial Node

Bio-Protocol, 2020
The cardiac conduction system allows the synchronized propagation of electrical activity through heart muscle. This is initiated by the spontaneous activity of the specialized pacemaker cells of the sino-atrial node (SAN).

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, Volume 13, Issue 56, 9 October 2026.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Functional and morphological organization of the cat sinoatrial node

, 1986
The feline sinoatrial node has a unifocal impulse generation as previously described for rodents. Its main component is collagen. The primary pacemaker consists of at most 2000 cells, but appears to function normally with less than 500 cells.

Stepwise Localization of Non‐Pulmonary‐Vein Ectopy Using Cycle‐Length‐Based Activation Map Separation and Local Electrogram Morphology on the Affera System

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
On the Affera system, a single voltage‐map dataset containing both sinus and ectopic beats, collected without rhythm‐specific settings, can be separated by cycle length (coupling interval) into SR and PAC activation maps. Stepwise filtering by activation threshold (voltage‐per‐second, excluding far‐field potentials) and close‐unipolar QS‐like ...

Radiotherapy‐Induced Side Effects: Epidemiology, Pathogenesis, Prevention and Treatments

MedComm, Volume 7, Issue 10, October 2026.
Radiotherapy for malignancies frequently injures the organs’ systems through oxidative stress, fibrosis, inflammation, and vascular damage. This review systematically maps the epidemiology, pathogenesis, and emerging therapies to propose a mechanism‑network‑targeted framework for integrated, personalized care in radiation oncology.
