What is Arrhythmia? Abnormally with: Speed (bradycardia vs. tachycardia) OR Rhythm: Origin (sinus vs atrial vs ventricular) Describe the Conduction pathway? 1) Electrical impulses begin at the SA node - under vagus nerve control: parasympathetic and then travel down to the AV node 2) AV node's refractory period acts as a "gate" to prevent excessive impulses from being conducted into the ventricles 3) From the AV node, the impulses then travel to the bundle of HIS 4) Action potentials sp...

Cardiac enzyme/marker interpretation (troponin, CK-MB, BNP) Troponin: Troponin is a protein in heart muscle cells that regulates muscular contraction. When the heart muscle is damaged, as in a heart attack, troponin is released into the bloodstream. Troponin levels can become elevated 3-4 hours after a heart attack and can remain elevated for up to 14 days. Therefore, it is a highly specific indicator of heart damage. CK-MB (Creatine Kinase-MB): CK-MB is a form of creatine kinase found mostl...
