Epinephrine Dosing, Clearly Explained

CARDIOLOGY, ECG, Pharmacy and Therapeutics

Epinephrine dose in mg vs volume to be given Epinephrine 1:10,000 means 1g : 10,000ml. That is the same as 1000 mg: 10,000ml. Which is the same as 1mg:10ml. That means in an ACLS code situation if you want to give 1mg of epinephrine, you would actually draw 10ml of...

ECG Causes of ST-segment elevation: ELEVATION

CARDIOLOGY, ECG, MNEMONICS

Electrolyte abnormalities Left bundle branch block Aneurysm of left ventricle Ventricular hypertrophy Arrhythmia disease (Brugada syndrome, ventricular tachycardia) Takotsubo/Treatment (iatrogenic pericarditis) Injury (myocardial infarction or cardiac contusion)...

Functional Capacity

CARDIOLOGY

The patient’s functional capacity has been shown to correlate well with maximal oxygen uptake on treadmill testing. Functional status or capacity is important to know because exercise capacity is a reliable predictor of future cardiac events. Functional capacity...
