EKG and Electrical Pathway of the Heart

Interpret this Rhythm:

• Normal sinus rhythm

• Ventricular fibrillation

• Sinus Brady with PAC's

• Sinus Bradycardia

Damage or interference in the electrical pathway through the septum altering the contraction of the ventricles is known as:

• bundle branch block

• atrial fibrillation

• ventricular tachycardia

• atrial flutter

Transfers distance on an electrocardiogram; in conjunction with the appropriate scale, the heart rate can be determined. An instrument that is useful in measuring distances on an EKG tracing.

• Dutration

• Amplitude

• Large Boxes

• Calipers

Identify the tracing

• Atrial Flutter

• AV block: 1st degree

• Atrial Fibrilattion

• Sinus Tachycardia

Also known as the baseline, it is best determined by drawing a line between the end of the T and beginning of the P wave.

• P wave

• isoelectric line

• SA node

• Av node

The relaxation phase of the heart that prepares the heart for another depolarization.

• wave

• segment

• repolarization

• depolarization

Flat line seen on the electrocardiogram.

• Bipolar Line

• Unipolar Line

• Isoelectric Line

• Asystole

The period between specific electrical activities of the heart that is recorded on the EKG

• segments

• isoelectric

• intervals

• atrial kick

The downward presentation of waveforms on the EKG tracing that is located below the isoelectric line.

• negative deflection

• positive deflection

• isoelectric line

• repolarization

The portion of waveforms in an EKG tracing located above the isoelectric line.

• negative deflection

• positive deflection

• repolarization

• isoelectric line
