The Essential Vocabulary of Rhythm Interpretation

Think of rhythm interpretation as a complex puzzle. To solve it, you need to understand the individual pieces and how they fit together. These "pieces" are the key entities we’ll explore below, categorized for clarity.

Core Concepts

• ECG/EKG: This stands for electrocardiogram, a non-invasive test that records the electrical activity of the heart over a period of time using electrodes placed on the skin. It’s the primary tool for rhythm interpretation.

• Heart Rate: This is the speed at which the heart beats, measured in beats per minute (bpm). Understanding normal heart rate ranges (typically 60-100 bpm in adults) is crucial for identifying abnormalities.

• Arrhythmias: These are abnormal heart rhythms caused by disturbances in the heart’s electrical system. Recognizing different types of arrhythmias is the ultimate goal of rhythm interpretation.

Specific Rhythms: A Closer Look

Understanding different rhythms allows us to be able to diagnose and treat.

• Sinus Rhythm: This is the normal heart rhythm, originating from the sinoatrial (SA) node, the heart’s natural pacemaker.

• Atrial Fibrillation (AFib): A common arrhythmia characterized by rapid, irregular atrial activity.

• Ventricular Tachycardia (VTach): A potentially life-threatening arrhythmia originating in the ventricles, marked by a rapid heart rate.

• Bradycardia: A heart rate slower than 60 bpm.

• Tachycardia: A heart rate faster than 100 bpm.

Decoding the ECG Waveforms

The ECG tracing is made up of distinct waveforms, each representing a specific electrical event in the heart.

• P Wave: Represents atrial depolarization (the electrical activation of the atria).

• QRS Complex: Represents ventricular depolarization (the electrical activation of the ventricles).

• T Wave: Represents ventricular repolarization (the recovery of the ventricles to their resting state).

• PR Interval: The time it takes for the electrical impulse to travel from the atria to the ventricles.

• QT Interval: The time it takes for the ventricles to depolarize and repolarize.
