Cardiac Rhythm Strips and EKG Overview
Study of a patient's EKG may indicate normal or abnormal conditions. Abnormal rhythms are called arrhythmia or sometimes, dysrhythmia. Arrhythmia is an abnormally slow or fast heart rate or an irregular cardiac rhythm.
The EKG waveform has several pieces for each heart beat. These waveform features are called P, Q, R, S, T and U.
The first movement of the ECG tracing (usually upwards) is the P wave, indicating electrical activity that triggers atrial contraction. The QRS components mark ventricular depolarization and contraction and are usually of greater amplitude than the P wave. T wave is normally a smaller (than QRS) upwards waveform, indicating ventricular repolarization.
Cardiac Rhythm Strip Reference Guide
Our cardiac rhythm strips guide provides information on essential dysrhythmia categories:
- Premature Atrial Contractions
- Atrial Flutter
- Atrial Fibrillation
- Multifocal Atrial Tachycardia
- Wandering Atrial Pacemaker
- Junctional Rhythm
- Junctional Tachycardia
- Premature Junctional Contraction
- Supraventricular Tachycardia
- Premature Ventricular Contractions (several type of)
- Accelerated Idioventricular Rhythm
- Ventricular Fibrillation
- Monomorphic Ventricular Tachycardia
- Polymorphic Ventricular Tachycardia
- Heart Blocks
- First Degree Heart Block
- Second Degree Heart Block, Type 1 - Mobitz I
- Second Degree Heart Block, Type 2 - Mobitz II
- Third Degree Heart Block
- Sudden Arrhythmic Death Syndrome
For each type, we offer EKG cardiac rhythm strips.
A tabular summary of the cardiac rhythm is provided and electronic calipers can be used to evaluate a strip.
