T wave inversion describes a small wave on the tracing pointing down instead of up. In several of the heart’s twelve viewpoints that is completely normal. What matters is which ones, and whether it is new.
Left ventricular hypertrophy, or LVH, is commonly seen on ECG reports and often means less than it sounds. The tracing measures electrical signals, not muscle thickness. Here is what the finding describes and what usually settles it.
n ECG report mentioning Q waves or a possible old heart attack is usually a normal variant. A cardiologist explains what the finding actually means.
First-degree AV block is a common ECG finding that sounds alarming but is usually harmless. Here is what it means, what causes it, and when further investigation is warranted.
A left bundle branch block is an electrical finding on an ECG, not a blocked artery. Prof. Peter Barlis explains what it means, what causes it, and when it matters.
The ECG is the most widely performed cardiac test in the world, quick, painless, and remarkably informative. Here is what it measures and what the results actually mean.
A normal ECG when you feel well does not rule out an arrhythmia. This guide explains the monitoring options available, from Holter monitors to implantable loop recorders.
Second-degree AV block means most signals reach the lower chambers of the heart and the occasional one does not. Some causes are entirely benign. Here is what the finding describes and what usually happens next.
In complete heart block the top and bottom of the heart stop communicating, and a backup rhythm takes over. It is serious, and it is also among the most fixable problems in cardiology.
