What happens to murmur w/ Inspiration
inc’d flow to R side of heart, all R sided murmurs increase
What happens to murmur w/ Expiration
Inc’d flow to L side of heart - all L sided murmurs increase EXCEPT HOCM &MVP DECREASE
Increased volume, increases murmurs except in
HOCM/MVP (decrease)
What positions cause increased volume return to heart?
Sitting, squatting, leg raising
What positions cause decreased volume return to the heart?
Standing, Valsalva
Handgrip
increases afterload, increases flow to murmurs that flow backward (AI, MR, VSD)
What happens to murmur during handgrip or phenylephrine? MR? MVP? HOCM?
- Handgrip increases afterload, LV cavit size increases so … volume increases. MR –> increases MVP —> duration of murmuer decreases, intensity incr HOCM –> decr murmur ALL murmurs increase including MR Except: dec’s HOCM, MVP, AS
What happens to murmurs with amyl nitrate use? MVP? HOCM? AS? MR?
Decreaes afterload, so its easy for blood to be pushed into systemic cir, LV cavity decreased so… volume decr MVP –> duration of murmur increases, intensity decr. HOCM –> incr murmur AS –> incr murmur MR –> decr murmur
What happens to murmur post PVC? HOCM? MVP? AS murmur?
post PVC volume potentiation and decreased afterload –> rapid emptying. Volume decr. HOCM –> murmur incr MVP –> duration of murmur incr., intensity decr AS murmurs –> murmur will incr
What happens to blood that returns to heart during valsalva maneuver
Increases intrathoracic pressure and DEcreases blood return to heart

Pt p/w CP - AWMI tx’d in CCU w/o complications, EF 30%, on D/C what meds
- ASA - plavix - BB - ACEI, - statin - ICD ( 40 days later - if high risk for VT then wear lifevest)
Pt had MI, stabilized - few months later. stress test abnormal - underwent cath - 70% stenosis LCx- started on ASA - what will incr long term survival?
start Statin (NOT CABG or PTCA)
Complications of MI (arrythmia)
< 48hrs: - VT (runs: observe. no incr mort. sustained=ischemic: stable –> IV lidocaine/amio. unstable: cardioversion) then back to cath lab. - NSVT - Blocks >48hrs: - VT (scar tisssue –> ICD maybe in 3months - NSVT
Complication of MI (mechanical ruptures)
- Papillary muscle rupture -> Acute MR - Septal rupture -> Acute VSD - Free wall rupture -> Tamponade
Ventucular arrythmias during acute MI
Ventricular ectopy or NSVT during AMI should NOT be treated VT/VFib occuring within 24 hrs of MI are independent risk factors for in house mortality BUT not risk for subsequent mortality from arrhthmia after d/c These DO NOT NEED long term antiarrhythmic therapy
Pt pw CP - EKG shows MI tx’d with tPA, heparin, nitrates, BB, ACEi - w/in 24 hrs pt has NSVT <30s wtd?
Observe
Mechanism of reperfusion arrhythmias?
Triggered activity; change in cardiac frequency due to accumulated Ca+
