A few days after drinking, the ECG is usually accurate.
The half-life of alcohol metabolism in the human body is 6 hours, generally after five half-lives, alcohol can be metabolized more than 98%, so after 1 to 2 days, alcohol is basically metabolized from the body, and no longer significantly affects the performance of the body’s organs, and will not affect the performance of the electrocardiogram, etc., so at this time to do the electrocardiogram is generally no effect.
Electrocardiogram is one of the most common clinical tests, and its wide range of uses makes it an important means of helping to diagnose arrhythmias, myocardial ischemia, myocardial infarction, myocardial hypertrophy, and many other cardiac problems.
It is recommended that you stop drinking alcohol 2 days prior to having an ECG or other test to avoid affecting the accuracy of the test.
