Telemetry Rhythms Overview

These flashcards cover key concepts related to telemetry rhythms, including definitions, characteristics, treatments, and classifications.

What is the normal PR interval range for a normal sinus rhythm?

The normal PR interval range is 0.12 to 0.2 seconds.

What heart rate range is classified as normal sinus rhythm?

The heart rate for normal sinus rhythm is between 60 to 100 beats per minute.

Describe the appearance of P waves in normal sinus rhythm.

P waves are upright and precede every QRS, with all P waves looking the same.

What defines sinus bradycardia in terms of heart rate?

Sinus bradycardia is defined as a heart rate less than 60 beats per minute.

What is the treatment protocol for unstable sinus bradycardia?

Administer atropine 0.5 mg IV push every 3 to 5 minutes, up to a maximum of 3 mg.

What does the presence of a heart rate of 136 indicate in telemetry?

This indicates sinus tachycardia.

What are the characteristics of atrial fibrillation (AFib)?

Irregular rhythm, inconsistent P waves, and quivering atria causing no definitive P waves.

How is atrial flutter characterized in telemetry readings?

The presence of F waves (flutter waves) that create a sawtooth appearance.

What is a key treatment consideration before cardioversion in AFib?

Patients need to be anticoagulated to prevent clots from traveling to the brain.

What are premature atrial complexes (PACs)?

PACs are early heartbeats caused by the atria firing earlier than normal.

What indicates a compensatory pause after a PAC?

A momentary pause in the heart's rhythm after the PAC occurs.

What defines premature ventricular complexes (PVCs)?

PVCs are wide and bizarre beats caused by early contractions of the ventricles.

What is the RMT phenomenon in relation to PVCs?

The RMT phenomenon occurs when a PVC happens at the peak of the T wave, potentially leading to V tach.

What is ventricular tachycardia (VTAC)?

VTAC is a fast ventricular rhythm occurring over 150 beats per minute, with wide and bizarre QRS complexes.

Describe how you would treat a stable patient with VTAC.

Monitor closely and administer amiodarone 150 mg over 10 to 15 minutes.

What defines asystole in telemetry readings?

Asystole is a complete lack of electrical or mechanical activity of the heart.

What is the primary treatment for asystole?

CPR and epinephrine; do not shock asystole.
