Poor (slow) R Wave Progression

CARDIOLOGY, ECG

Poor R wave progression (PRWP) refers to the absence of the normal increase in the size of the R wave in the precordial leads from lead V1 to V6. Normal or expected pattern As you go from V1 to V6, the height of R wave normally becomes progressively taller from leads...

Tachyarrhythmias Definition: Ventricular rate > 100. Based on QRS duration, they are divided into narrow-complex (QRS < 120 ms) or wide-complex (QRS >120 ms). There are further divided into regular or irregular rhythms. Mechanisms for tachyarrhythmias...

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)...

The AV blocks Clearly Explained

CARDIOLOGY, ECG

AV blocks are also called junctional blocks, nodal blocks, or heart blocks.  AV blocks happen when the electrical current that is being transmitted from the atrium to the ventricles is held in the AV node for a little too long or so long that it’s not even...
