Insights

Topsy-turvy heart is a rare condition where the heart rotates clockwise. This case series details the electrocardiography (ECG) findings in three patients diagnosed with this unique congenital heart defect.

Area of Science:

  • Cardiovascular Medicine
  • Medical Imaging
  • Pediatric Cardiology

Background:

  • Topsy-turvy heart (TTH) is an extremely rare congenital cardiovascular malformation.
  • It involves clockwise rotation of the heart around its longitudinal axis, resulting in superoinferior ventricle positioning.
  • Diagnosis often relies on advanced imaging, but noninvasive methods are crucial for early detection.

Purpose of the Study:

  • To describe the 12-lead electrocardiography (ECG) findings in patients with Topsy-turvy heart.
  • To evaluate the utility of ECG as a diagnostic aid for TTH.
  • To contribute to the limited literature on the electrocardiographic presentation of TTH.

Main Methods:

  • A case series approach was used.
  • Detailed analysis of 12-lead ECG data from three patients diagnosed with Topsy-turvy heart.
  • Correlation of ECG findings with anatomical diagnosis.

Main Results:

  • Specific ECG patterns indicative of TTH were identified across the three patients.
  • The findings highlight characteristic electrical axis deviations and chamber abnormalities.
  • ECG provided valuable diagnostic clues in the presented cases.

Conclusions:

  • Electrocardiography can offer significant insights into the diagnosis of Topsy-turvy heart.
  • ECG findings in TTH patients present a distinct pattern that warrants recognition.
  • This case series underscores the importance of considering ECG in the diagnostic workup of rare cardiac malformations.

Electrocardiogram01:29

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Dysrhythmias III: Characteristics of Dysrhythmias

Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Electrophysiology of Normal Cardiac Rhythm01:19

Electrophysiology of Normal Cardiac Rhythm

The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

Electrocardiogram Fundamentals

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...

Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
