Electrocardiogram ECG

The ECG shows the heart’s electrical activity as line tracings on paper. It’s the
recording of electrical activity of the heart. ECG is an instrument which is used to
record the electrical current generated in the heart. By means of this instrument, the
electrical current generated in the heart is conducted to remote by connecting any
two parts of the body with this instrument. The connections are called as leads they
are.
A normal ECG contains waves, intervals, segments and one complex, as defined
below. Wave: A positive or negative deflection from the baseline that indicates a
specific electrical event. The waves on an ECG include the P wave, Q wave, R wave, S
wave, T wave and U wave. Interval: The time between two specific ECG events.

The intervals commonly measured on an ECG include the PR
interval, QRS interval (also called QRS duration), QT interval
and RR interval. Segment: The length between two specific
points on an ECG that are supposed to be at the baseline
amplitude (not negative or positive). The segments on an ECG
include the PR segment, ST segment, and TP segment.
Complex: The combination of multiple waves grouped
together. The only main complex on an ECG is the QRS
complex. The P wave indicates atrial depolarization. The QRS
complex consists of a Q wave, R wave, and S wave and
represents ventricular depolarization. The T wave comes after
