ECG Chapter 27

facilitation of the transmission of electrical impulses of the heart

Normal sinus rhythm

Time from end of atrial depolarization to beginning of ventricular depolarization

Time from end of ventricular depolarization to beginning of repolarization of ventricles

AVL, AVR & AVF

Represents contraction of ventricles

Electrical voltage received by the electrocardiograph & changed to mechanical motion

artifact with small spiked consistent lines

Standardization mark?

RECORDING OF ELECTRICAL ACTIVITY OF THE HEART

Period of time when the heart rests

Time from beginning of atrial depolarization to beginning of ventricular depolarization

How many wires?

Pt discomfort, apprehension of pt & talking or coughing

How many leads on a standard electrocardiogram?

This monitors heart rate and rhythm during daily activities and assesses pacemakers?

Portion of the ECG between two waves

Time interval from beginning of vent. depolarization to end of repolarization of ventricles

Bipolar leads?

Which lead wire is located at the anterior axillary line?

The ECG paper moves super fast at about...

Represents electrical recovery of ventricles

Represents contraction of the atria

One complete heartbeat

Larger than normal Q wave and elevated ST segment....
