Chest pain and ST-segment abnormalities on ECG are among the most alarming findings in the emergency department. However, this case underscores an important principle: neither ST elevation nor widespread ST depression is synonymous with acute coronary occlusion. A thorough assessment of underlying physiology is essential to avoid misdiagnosis and inappropriate management. Case Presentation A man in his 70s with known peripheral arterial disease presented with chest discomfort

A pacemaker is a small electronic device that keeps the heart beating at a safe and stable rhythm when the body’s own electrical system fails. In this complete, clinically accurate guide, you’ll learn exactly how a pacemaker works , when it is used , and what healthcare professionals should look for during a pacemaker check - including sensing, capture thresholds, and lead impedance. Whether you’re a clinician, student, or simply curious, this article provides a clear and re

Case Presentation An 80-year-old man with hypertension and type 2 diabetes was found confused and somnolent at home. On EMS arrival, his blood pressure was 73/46 mmHg and heart rate fluctuated between 25 and 50 beats per minute. The ECG demonstrated a wide-complex bradycardia (rate 26). Atropine had no effect. He received intravenous adrenaline. On hospital arrival, the patient appeared pale, cold and hypotensive, with clinical signs of pulmonary edema and acute kidney injury

Acute Chest Syndrome and Right Ventricular Failure in a Patient with Sickle Cell Disease Case Presentation A man in his 40s from West Africa was admitted with diffuse pain throughout his body, including the chest. He had recently completed a long flight from Africa to Norway. On admission, he appeared clammy, in significant pain, and somnolent but easily arousable. Physical examination revealed no specific findings, but the patient appeared acutely ill and required supplement

A 62-year-old man with a history of deep vein thrombosis and known factor V Leiden mutation was admitted with exertional, squeezing chest pain. The chest pain subsided, but the dyspnea persisted. On admission he was hemodynamically stable with a heart rate of 90/min and a blood pressure of 130/90 mmHg. He was asymptomatic at rest but became clearly dyspneic when walking to the bathroom. Sinusrythme. T-inversions in leads V1-V3. T-inversion i lead III. S-wave in lead 1. The EC

Case Presentation A woman in her 20s was admitted with sudden-onset palpitations lasting approximately three hours before arrival. On admission, she was clammy, cold, and diaphoretic, and reported pre-syncopal episodes. Blood pressure was 137/95 mmHg, and heart rate approximately 200 bpm. The admission ECG showed a wide-complexed, irregular tachycardia. Irregular wide-complexed tachycardia - Pre-excited AF Same ECG - More complexes (Standard leads) Same ECG - more complexes (

A man in his 70s with a history of myocardial infarction was admitted with progressive dyspnea and findings consistent with heart failure. On admission, he had a regular tachycardia at approximately 116 bpm. ECG showed atrial tachycardia, and echocardiography revealed reduced left ventricular function with an ejection fraction (EF) of about 30%. Atrial tachycardia, 116 beats/min Apical 4-chamber view - The septal wall and apex are thin after previous myocardial infarction and

A previously healthy man in his 40s was admitted with chest pain considered atypical. The ECG showed ST elevations in aVL and in leads V2–V3, as well as ST depression in II, III, and aVF. T-wave inversions were also present in V3–V6. Despite these striking changes, the patient had preserved and tall R waves in the precordial leads. Echocardiography revealed no regional wall motion abnormalities, and troponin was as low as 4 ng/L. Because of the pronounced ECG changes and ches
