Insights

Sub-clinical cardiac involvement is common in leptospirosis, affecting nearly half of patients. Electrocardiogram changes indicate myocardial issues, necessitating monitoring, especially in acute kidney injury cases.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Internal Medicine

Background:

  • Leptospirosis is a zoonotic infection with potential systemic complications.
  • Cardiac involvement in leptospirosis is not well-characterized.
  • Electrocardiographic (ECG) findings can indicate myocardial dysfunction.

Purpose of the Study:

  • To investigate the prevalence and nature of electrocardiographic abnormalities in patients with leptospirosis.
  • To assess the significance of these findings for sub-clinical cardiac involvement.

Main Methods:

  • Retrospective analysis of electrocardiograms (ECG) from patients diagnosed with leptospirosis.
  • Evaluation of ECG parameters including rhythm, P-QRS-T complexes.
  • Correlation of ECG findings with clinical presentation and renal status.

Main Results:

  • Electrocardiographic abnormalities were observed in 46% of leptospirosis cases.
  • Abnormalities included cardiac rhythm disorders and alterations in P-QRS-T complexes.
  • These changes suggest sub-clinical myocardial involvement.

Conclusions:

  • Leptospirosis frequently causes sub-clinical cardiac involvement, detectable by ECG.
  • Serial ECG monitoring is recommended for patients with acute renal failure (oliguric) and other presentations of leptospirosis to detect cardiac changes.

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 the T...

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...

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 to...

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 minute.
Dysrhythmias IV: Characteristics of Bradyarrhythmias01:18

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

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...
