CS- S1B2
Name | Features |
---|---|
Class I | No limitation in physical activity; slight fatigue |
Class II | Slight impairement of physical activity |
Class III | Marked limitation of physical activity; comfortable at rest, but less than ordinary activity causes symptoms |
Class IV | Symptoms may be present even at rest; unable to engage in any physical activity w/out discomfort |
Most common symptoms of heart disease | Dyspnea, chest pain, palpitations, syncope, fatigue, diaphoresis, cachectic appearance |
Dyspnea | Difficulty breathing; pp by exertion, result from left atrial+pulmonary venous pressure or hypoxia; worsening of left atrial hypertension=pulmonary edema;quantified by amount of activity that precipates it |
Orthopnea | Dysnea that occurs in recumbency; result from increase from central venous pressure |
Paroxysmal nocturnal dyspnea (PND) | SOB that occurs abruptly;30-2h after going to bed&is released by sitting or standing up |
Ischemia | inadequate circulation of blood to the myocardium;usu as result of coronary a. disease d/t stenosis;sensation of discomfort;last 5-20min;tightness, pressure |
Angina Pectoris | Coronary a. go to different parts of the heart;precordial chest pain,usu pp by stress or exertion, relieved rapidly by rest or nitrate drugs(nito=veno dilator)obstruct of coronary vess(atherosclerotic heart disease if no obstruc: L ventricular hypertrophy |
Pain of Myocardial Infarction | if pain last longer than 20 mins then MIA |
MI | Sudden insufficiency of arterial blood supply to the heart muscle as result of occlusion of coronary a; anxiety/sense of uneasiness;retrosternal,L precordial, protracted ischemic symptoms |
Ischemic Pain | pp by exertion;usu relieved by rest, not related to position or respiration;if can reproduce pain by palpating then NOT heart pb; also seen with hypertrophy of either ventricles, aortic disease |
Atypical Chest Pain | Myocarditis, cardiomyopathy, Primary pulmonary hypertension, Mitral valve prolapse |
Palpitations | Awareness of the heartbeat;manifestation of cardiac abnormalities that increase stroke volume; cardiac dysrhytmias, PVC,SVT(supraventricular)or atrial ventricular tachycardia (VT) |
PVC | premature ventricular contraction |
Syncope | Loss of consciousness, faint |
Cadiogenic syncope | at AV=no heartbeat;usu fr sinus node block AV conduction or ventricular febrillation(heart quivering, no organized activity);few prodromal sympt;cardiomyopathy;no premonitory sx: not postural hypotension |
Neurocardiogenic syncope=vasovagal syncope | inappropriate increase in vagal efferent activity, follow brief period of duaphoresis, abrupt in onset like arrythmia-induced syncope |
Diaphoresis | hypotension or hyperadrenergic state; seen in PERICARDIAL TAMPONADE |
Cachectic appearance | chronic low cardiac output states |
Central Cyanosis | d/t aterial desaturation, low output state |
Peripheral Cyanosis | Reflects impaired tissue delivery of adequately saturated blood;poycythemia,peripheral vasoconstriction |
Systolic pressures below 90 or more than 140 | need follow-up |
Tachypnea | nonspecific=respiration rate more than 16/min;consider pulmonary disease+heart failure |
Diminished peripheral pulses | result from arteriosclerotic peripheral heart disease; accompanied by localized bruits |
Carotid pulse | valuable to assess L ventricular dunction |
Delayed upstroke | aortic stenosis |
Bisferiens quality | 2 palpable peaks, hypertrophic obstructive cardiomyopathy, mixed aortic regurgitation & stenosis |
Pulsus alternans | a,plitude of pulses alternated every other beat during sinus rhythm; occurs when cardiac contractility is very depressed or w/ large PERICARDIAL EFFUSIONS |
Pulsus paradoxus | a decrease in systolic blood pressure during inspiration more than normal 10mm Hg, valuable sign of chronic obstructive pulmonary disease (COPD) |
Jugular Venous Pulsations | Insight into right atrial pressure;if more than 3cm above Angle of Louis: increased CVP; if rise more than 1cm w/ sustained R upper abdominal quadrant pressure (hepatojugular reflex)=increased central blood volume |
Crackles | heard at lung bases; sign of congestive heart failure(CHF) |
Wheezing and Rhonchi | suggest obstructive pulmonary disease but may occur in L heart failure (cardiac asthma) |
Pleural Efllusions | w/ bibasilar percussion, dullness, and reduced breath sounds = commin in CHF |
Edema in heart disease | results from elebated right atrial pressures |
Pulse oximetry | shown thru capillaries, more it absorbs shows oxygen concentration in blood, red light |
S1 | Mitral & Tricuspid valves |
S2 | Pulmonary & Aortic valves |
3rd heart sound | mid-diastolic sounds |
4th heart sound | atrial gallop- abnormal |
S3 | during rapid filling phase of ventricle, after closure of aortic and pulmonary valves;may be normal in children, pregnant; heart failure(ventricle dysfxn),mitral and tricuspid regurgitation(increase flow during rapid filling phase of ventricles) |
S4 | Triple cadence to heart sounds at rate of 100/min; valve snaps back; indicative of serious disease; stiff or non-compliant ventricle |
Clicks | high-pitched sounds. Ejection sounds |
Murmurs | valvular disease; pansystolic when merge w/ 1st heart sound and persist thru all systole |
Ejection murmurs | when they begin after the 1st heart sound and end before the 2nd |
Innocent murmurs | often vary w/ inspiration, diminish in upright position; most often heard in thin individuals-esp. women |
Thrills | palpable vibrations associated with murmurs |
