Q12 of 42 Page 104

How will you interpret an electrocardiogram (ECG) in which time taken in QRS complex is higher.

In an ECG, QRS complex represents ventricular depolarisation. Normal duration of QRS complex is less than or equal to 0.10 seconds. If QRS complex is longer than 0.10 seconds and the wave is enlarged it indicates the person is having Myocardial Infarction or Heart Attack.
