J wave and hypothermia

Abstract:
Hypothermia can result from exposure to a cold environment (e.g., accidental drowning) or it can be induced and used as a brain protection strategy (e.g., therapeutic hypothermia). One common ECG presentation with hypothermia is the J wave, which is related to the altered cellular activities during hypothermia. A case study is used in this article to illustrate the presentation of a J wave with a patient experiencing hypothermia.

Pharmacological Methods of Reducing Fever:
Homeostatic Imbalances in Body Temperature
Increased Body Temperature
Assessing Body Temperature - Temporal Artery
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...
Blood Pressure Imbalances and Circulatory Shock
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
