Sinus tach s - Study guides, Class notes & Summaries

Pacemakers of the Heart correct answer: Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV nod...

Coronary sinus - Answer Main venous drainage vessel of the heart AV Valves - Answer Tricuspid and pulmonic Systolic murmur - Answer Aortic stenosis Mitral regurgitation Key treatments in management of HF - Answer -ACE -BB -Diuertics Pericardial tamponade - Answer -Equalization of left & right atrial pressures (CVP and PAOP) -Hypotension -Distended neck veins -auscultate heart sounds frequently to identify muffling of heart sounds in pericarditis prior to tamponade Pericarditis tx - A...

Nitroprusside purpose - Answer- decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action - Answer- contractility Dopamine at a low-end dose "renal dose" - Answer- 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose - Answer- 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose - Answer- greater than 10mcg/kg/min vasoconstriction and increases BP Dopamine and Levophed inf...

What does the SA node initiate - - P wave (if none, SA not responsible for electrical conduction) (atrial depolarization) What does the QRS complex represent? - ventricular depolarization (vent contraction) (none=no pulse) (don't see atrial repolarization but it occurs, as it is not the strongest thing to occur) What does the U wave indicate? - indicates hypocalemia, not conductio issue it would be seen with electrolyes (digoxin) Is it normal to not see part of the Q, R, or S complex -...

What is the end-diastolic volume? Preload High preload causes? (2) fluid overload, LV failure what is the treatment for high preload? diuretics What is the treatment for low preload (hypovolemia, tricuspid/mitral valve stenosis)? (2) fluids, vasoconstrictors What is the resistance of the blood leaving the heart? afterload Low K increases the risk of ________ toxicity digoxin how to calculate MAP? (SBP + 2DBP)/3 what is the #1 sign of pulmon...
