Irregular Heartbeat

Definition of Irregular Heartbeat

An irregular heartbeat can be a heart rate that is too slow or too fast or the rhythm may be an irregular rhythm from beat to beat.

Diagnosis of Irregular HeartBeat

While there are several types of tests for irregular heartbeat; in this website, we will discuss one particular test: electrocardiogram (EKG). Our training materials include the following:

  • HeartBeat Basics
  • Irregular Heartbeat Drills
  • Graded Quiz

Heart Rhythm Basics

The lessons in this course will help you learn to determine heart rate from an EKG tracing and assessing cardiac rhythm. Discussion and examples will help you observe P-wave forms and measure EKG waveform intervals and segments. You can also practice what is taught in each lesson using that lesson's quiz.

Irregular Heartbeat Drills

Try our heartbeat practice strips to gain confidence and speed in arrhythmia interpretation. After each answer, scoring and detailed coaching is provided. With 100+ EKG strips, this drill can be repeated many times.

Irregular Heart Rhythm Quiz

The irregular heartbeat quiz consists twenty EKGs that require assessment. With each answer, feedback is given. A report with all twenty questions and correct answers is provided at the completion of the quiz.

Patient ECG Monitor Challenge

A moving EKG waveform in this quiz is used to introduce you to observing a patient monitor.

Types of Irregular Heartbeats

The origin and heart rate are used to help classify irregular heart rhythms.

  • Fast (over 100 beats per minute) heartbeats are called tachycardia. Tachycardias can originate in the atria or ventricles.
    • Ventricular arrhythmias include:
      • Long QT syndrome
      • Premature ventricular contractions
      • Ventricular fibrillation
      Supraventricular (atrial) arrhythmias include:
      • Atrial fibrillation
      • Atrial flutter
      • Supraventricular tachycardia
      • Wolff-Parkinson-White syndrome
  • Bradycardia describes slow heartbeats (under 60 beats per minute).

    • Types of bradycardia include""
      • Conduction Block
      • Sinus bradycardia
      • Sick Sinus Syndrome

  • Premature Beat is an extra beat, occurring earlier than normal.
