Summary
This case report details severe multi-vessel coronary spasm during epicardial mapping in a patient with chronic Chagas cardiomyopathy. This complication highlights potential risks during electrophysiological procedures in such patients.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiovascular Disease
Background:
- Chagas cardiomyopathy is a significant cause of heart disease in endemic regions.
- Epicardial mapping is an invasive electrophysiological procedure used to diagnose and treat cardiac arrhythmias.
- Coronary artery spasm can lead to myocardial ischemia and serious cardiac events.
Purpose of the Study:
- To report a rare complication of severe multi-vessel coronary spasm during epicardial mapping.
- To highlight the potential risks associated with electrophysiological procedures in patients with Chagas cardiomyopathy.
Main Methods:
- A case report detailing a patient undergoing epicardial mapping for chronic Chagas cardiomyopathy.
- Description of the occurrence and management of severe multi-vessel coronary spasm.
Main Results:
- Severe multi-vessel coronary spasm occurred during the epicardial mapping procedure.

3.2K
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.

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

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

01:25Correlation between ECG and Cardiac Cycle
8.2K
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...

2.4K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
