Day 4 - CV2 Arrhythmias, HF, Valvular, Pericardial Flashcards
EKG Rhythm - Narrow QRS not associated with p waves; HR 60
3rd degree heart block; aka Junctional rhythm
Wide QRS not associated w/ p waves; > 40 but less than 100 HR
Accelerated ventricular rhythm
Chaotic, Erratic wide QRS
Ventricular fibrillation
Narrow QRS not assoc. w/ p waves; HR > 100
Junctional tachycardia
Wide QRS not assoc. w/ p waves; Rate 20-40
Ventricular rhythm
Wide QRS not assoc w/ p waves; Rate > 100
Ventricular tachycardia
Narrow QRS not assoc w/ p waves; Rate > 60 but
Accelerated junctional rhythm
Erratic QRS varies in amplitude in repeating pattern
Torsade de pointes
Wandering pacemaker vs. MAT
(1) Wandering pacemaker aka multifocal atrial rhythm: at least 3 different p wave morphologies, 100 (also, there’s MABradycardia, which is
PAC Tx
Observation; Stop caffeine if uncomfortable
Amiodarone pre-cautions
LFTs, PFTs (avoid if pre-existing lung disease), TFTs
Acute onset Afib w/ rapid ventricular rate in patient w/ WPW
Electrocardioversion or Procainamide
Complete independence of p waves from QRS. Next step is:
Pacemaker
PSVT Tx
Carotid massage (if no carotid artery disease), Valsava, IV Adenosine
Valves blood flow thru during systole
Aortic and pulmonic valves
Systolic murmurs
AS, PS, MR, TR, VSD,
Valves blood flow thru during diastole
Tricupsid, Mitral
Diastolic murmurs
TS, MS, PR, AR
Kussmaul sign v. Pulsus paradoxus
Both occur w/ inspiration; JVD w/ inspiration vs. Drop in systolic bp larger than 10 w/ inspiration; KS - decreased capacity of Right ventricle, seen in constrictive pericarditis (sometimes, cardiac tamponade); PP - decreased capacity of Left ventricle, seen in cardiac tamponade (sometimes, pericarditis)
