The junction between the termination of the QRS complex and the beginning of the ST segment.

A graph on which one or more particular lead is monitored to assess the rate and rhythm.

The R--R Interval is also known as:

This wave can be indicative of an electrolyte disturbance.

Isoelectric line that falls between the end of the P wave and ends before the start of the Q wave.

What is the least accurate way to check a heart rate on an EKG strip?

The first wave deflection seen on the isoelectric line.

Represents the line from the end of the QRS complex to the start of the T Wave.

This wave is thought to represent the repolarization of the Purkinjie Fibers.

Usually the central and most visually obvious part of the EKG.

Also known as the small box method.

This wave is not seen if tachycardia is present.

Negative waveform due to depolarization of the base of the ventricles

The 300 Method is the most accurate way to get a heart rate on the EKG.

Corresponds to the depolarization of the right and left ventricles of the human heart.

The period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex.

A combination of a wave and a segment, or a wave, segment and a complex.

Negative waveform due to the depolarization of the inter-ventricular septum.

Seen as a result of the conduction impulses traveling from the AV node to the Bundle of His.

Seen as a result of the repolarization of the ventricles.

Signifies the duration of one cardiac cycle.

Common way to check for heart rhythm (regular or irregular).

How is Atrial Rhythm measured?

Used for irregular heart rhythms.
