Aortic Regurg sx - -Head bobbing with pulse -wide pulse pressure 40 -water hammer pulse Aortic regurgitation causes - -HTN rheumatic fever endocarditis marfan syndrome and VAD S3 heard sound - fluid overload s4 heart sound - artium contract into noncompliant ventricle LV failure. A split heart sound is heard best during ___ - inspiration Mitral Insufficiency is a ___ murmur located at the ____ ICS - systolic 5th A patient with mitral insufficiency is prone to which of the following dysrhythmias? - A fibb What are causes of mitral regurg - Causes: MI Ruptured chordae tendineae Severe left heart failureHypertrophic cardiomyopathy Left ventricular hypertrophy MV prolapse Myxomatous degeneration Rheumatic fever Endocarditis Symptoms of mitral regurgitation - - fatigue -pulmonary congestion, orthopnea, dyspnea -Heart Failure, angina Mitral Valve Stenosis sx - -Left atrial enlargement ( showing increase P wave in lead II and notched P wave in lead V1) -pulmonary edema and congestion -Right vent failure -pink cheeks -A FIBB -DIASTOLIC MURMUR A patient jusr received a mitral valve replacement. What arrhythmias should we look for - Heart Block (very close to the bundle of his) and A fibb -be prepared to pace On an EKG with elevation in II, III, and aVf. you also see ST depression in V1. What type of MI is this - Inferior posterior. On an EKG with elevation in II, III, and aVf. you also see ST elevation in V1-V3. What type of MI is this - RIGHT VENTRICULAR!!!Use fluid blouses to increase BP These patient are preload dependent. Fluid first then +ionitrops What 2 AV blocks do you have to pace - Mobitz and 3rd How would you treat polymorphic V Tach - Magnesium (tornadoes) Your patient has Mitral regurgitation. You would expect them to have a high or low PAOP - High 16 how fast do you decrease BP in hypertensive urgency - Decrease BP by 25% in 1 - 2 hrs how fast do you decrease BP in HTN emergency - as fast as possible what a common adverse outcome of stenting of a thoracic aneurysm? - spinal cord ischemia signs of AAA rupture - tachy, pulsation of aorta in abdomen watch kidney fuinction panels for kidney damage What is Homan's sign? - Pain in calf with abrupt dorsiflexion of the foot while the knee is flexed at 90° associated with DVTs--- treat with anticoags What do these pacemaker modes mean DDD VVIAAI VVO - D D D Atria/ventricle paced, atria/ventricle sensed, pacing inhibited with intrinsic rhythm/beat V V I Ventricle paced, ventricle sensed, pacing inhibited with intrinsic rhythm/beat A A I Atria paced, Atria sensed, pacing inhibited with intrinsic rhythm/beat V V O Ventricle paced, ventricle sensed, will pace regardless of intrinsic rhythm/beat (dangerous!!! - possible R on T) Why do you have to give Mag slow for polymorphic Vtach - becuase it causes vasodilation What are the 5 Hs and 5 Ts with causing PEa - 5 H's: Hypovolemia Hypoxia Hypo/Hyperkalemia H + ion (acidosis) Hypothermia 5 T's: Thrombus: MI PE Tension pneumothorax Tamponade Toxicology (Drug OD) What is the goal aPTT on a heparin drip? - 50-80 seconds what is first line therapy for HTN - ace, arb, and diuretics patient has a BP difference of 25mmhg from the left and right arm. patient complains of ripped pain in the chest and back. What do they have - aortic dissection
