2024年10月8日 · Recognition of any of these killer ECG patterns should prompt expedited medical assessment and treatment. 25-year-old with exertional dizziness. Q1. What are the main abnormalities present on this ECG? Q2. What is the likely diagnosis? Q3. What should be done next? 17-year-old noticed “high” heart rate on Apple watch. Q1.

2024年10月8日 · The ECG shows: Regular broad complex tachycardia; Rate 130 bpm; Right axis deviation (+120 degrees) Hidden P waves buried in the ST-segments / T waves (best seen in leads II, aVF). These could be retrograde P waves from a junctional / ventricular rhythm or sinus P waves with an extremely long PR interval (360ms) Very broad QRS complexes (160ms)

2024年5月16日 · Vasospasm, local intermittent microvascular constriction, catecholamine–induced metabolic toxicity, transmural systolic wall tension and its the mechano–electric feedback can explain scaring ECG–pattern.

2019年11月22日 · One of the common interruptions in the ED is a request to “sign off” on an ECG of a patient who has been triaged but not seen by a doctor yet. Therefore, knowing deadly ECG patterns is an essential skill for emergency physicians, residents, as well as medical students who rotate in the emergency department.

2018年8月27日 · The ECG showed a regular narrow QRS tachycardia at 108 bpm suggestive of a regularized atrial fibrillation, with ST-segment elevation in aVR and less marked in V 1, with ST-segment depression in V 2 through V 6 and the inferior and lateral leads.

2017年8月3日 · Learn the ECG patterns for posterior MI, left main disease, the ominous isolated T-wave inversion in aVL, large upright T-wave in V1, and Wellen's warning. This full text article is mandatory reading.

2018年2月28日 · Yew leaves poisoning is a rare life‐threatening intoxication, whose diagnosis can be difficult. Initial symptoms are nausea, vomiting, abdominal pain, dizziness, tachycardia, muscle weakness, confusion, beginning within 1 hr from ingestion and followed by bradycardia, ventricular arrhythmias, ventricular fibrillation, severe hypotension, and death.

2022年9月19日 · Here we introduce the mnemonic “ABCDE Left Right”, a memory aid to help EM providers quickly recall seven ECG patterns of high-risk syncope: AV block, Brugada pattern, QTc prolongation, delta waves (Wolff-Parkinson-White), epsilon waves (arrhythmogenic right ventricular cardiomyopathy), left ventricular hypertrophy, and right ventricular strain.
