Summary
Electrocardiogram (ECG) abnormalities are common in Coronavirus disease-2019 (COVID-19) patients, indicating cardiac injury. These ECG findings aid in the early diagnosis and management of cardiovascular complications during the pandemic.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Diagnostics
Background:
- Coronavirus disease-2019 (COVID-19) is a multisystem illness impacting cardiovascular health.
- Myocardial injury in COVID-19 is linked to poor prognosis.
- Electrocardiogram (ECG) is a valuable bedside tool for assessing cardiac involvement.
Purpose of the Study:
- To investigate the prevalence and types of electrocardiogram (ECG) abnormalities in hospitalized COVID-19 patients.
- To identify potential associations between ECG findings and clinical characteristics.
Main Methods:
- A cross-sectional, hospital-based descriptive study was conducted.
- Electrocardiogram (ECG) recordings of 315 COVID-19 in-patients were analyzed upon admission.
- Clinical profiles were extracted from patient records.
Main Results:
- Significant ST and T segment changes were observed in 42.9% of patients.
- Rate abnormalities (36.5%) and short QRS complex (8.3%) were frequent.
- Ischemic ECG changes correlated with systemic hypertension and respiratory failure.
Conclusions:
- COVID-19 patients exhibit various ECG abnormalities, including ischemic changes, rate, rhythm, and conduction defects.
- ECG is a crucial, non-invasive tool for early detection and management of cardiac injury in COVID-19.
- The study highlights the utility of ECG in resource-limited settings during the pandemic.

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.

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...

01:30Pulse rhythm
973
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

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...

01:25Correlation between ECG and Cardiac Cycle
9.1K
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...

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...
