Summary
Electrocardiographic artifacts can mask life-threatening conditions like ventricular fibrillation in emergencies. Trans-thoracic ultrasonography proved vital in identifying this condition when ECG was uninterpretable.
Area of Science:
- Emergency Medicine
- Cardiology
- Medical Ultrasonography
Background:
- Electrocardiographic (ECG) artifacts are common in pre-hospital care, potentially leading to misdiagnosis.
- Accurate ECG interpretation is crucial for timely and appropriate patient management.
Observation:
- A case involving a victim of electrical injury presented with ventricular fibrillation masked by significant ECG artifacts.
- The persistent 50Hz domestic current caused the electrical injury and subsequent ECG interference.
Findings:
- Trans-thoracic ultrasonography successfully identified ventricular fibrillation despite the uninterpretable ECG.
- This case highlights the diagnostic utility of ultrasonography when ECG analysis is compromised by artifacts.
Implications:
- Ultrasonography may serve as a critical tool for diagnosing ventricular fibrillation in artifact-laden ECG scenarios.
- Emphasizes the importance of rigorous ECG device analysis and considering alternative diagnostic methods in challenging pre-hospital settings.

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...
01:29Dysrhythmias 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.

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
