Synonyms: Accidental hypothermia, Neurotensin-induced hypothermia, Endogenous cryogen-induced hypothermia, Hypoxia-induced hypothermia, Primary hypothermia, Secondary hypothermia Definition: The normal body temperature is around 37 c or 98.6 F. Hypothermia is defined as the lowering of core body temperature below 35°C or 95°F. Classification (Grading): Mild: 32°C to 35°C (90°F to 95°F) Moderate: 28°C…

ECG changes in Hyperkalemia
Synonym: Hyperpotassemia Definition: Serum potassium (K+) > 5 mEq/l Electrophysiologic basis of ECG changes: In patients with mild hyperkalemia, potassium conductance (IKr) through potassium channels is increased, which tend to shorten the AP duration and on the ECG causing tall tented T waves. With severe hyperkalemia, effect on RMP becomes…

Basics of ECG- Interpretation of waves and intervals
A normal ECG is electrical representation of a normal heart beat or sinus rhythm. The cardiac action potential causing deporalization and repolarization of various cardiac tissues gives a pattern of rhythic change is Electrocardiograph which can be used to diagnose different diseases of the CVS. Normal Rate The beats…
