Researchers have developed an AI tool that can help doctors predict who might develop a potentially fatal heart condition, just from an ECG. Subscribe to our newsletter for the latest sci-tech news ...

Q: I recently had an electrocardiogram as part of a routine physical exam. The report said I had a bundle branch block. What does that mean? Will I need a pacemaker? A: Bundle branch blocks are ...

Left bundle branch block (LBBB) is a type heart block. It results from a problem with the electrical conduction system that enables the heart to beat. It may cause no symptoms, but an ...

A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...

At times it can be difficult to distinguish "SVT with aberrancy" from ventricular tachycardia. This QRS morphology has a typical left bundle branch block pattern, is irregular and does not meet the ...

Complete heart block means that there’s a complete separation of electrical activity between the upper and lower chambers of the heart. Without prompt medical attention, it can be fatal. Your heart ...
