arrythmia apendx B

discriptions of rhythms

QuestionAnswer
tachicardias heart rate to fast to allow ventricles to fill completely before contraction
bradycardias heart rate to slow to maintain cardiac output
ventricular irritability erratic ventricular contraction is not effective enough to maintain stroke volume
stroke volume the amount of blood ejected with each contraction of the left ventricle
cardiac out put amount of blood pumped by the left ventricle in one minute stroke vol. X heart rate = liters per minute
NSR normal sinus rhythm does not produce symptoms
sinus bradycardia slow regular pulse, can cause sings/symptoms of decreased cardiac out put
sinus tachycardia rapid, regular pulse, probably asymptomatic possibly palpitations, dyspnea
sinus arhythmia irregular pulse, rarely causes symptoms
sinus bradycardia (CAN) precede blocks, asystole, precipitate escape rhythm, or ventr. irritability, caused by AMI, vagal stimulation, increased intercranial pressure, reflect normal athletic heart
sinus tachycardia (usually) compensatory responce to fever, activity, pain, anxiety, hypovolemia, heart failure ...Dangerous can extend infart
sinus arhythmia common in children and young adults
premature atrial complex (usually) benign, early sign of CHF, lead to atrial tachyarhythmias, causes include: fatigue, hypoxia, dig-toxicity, caffine, ischemia, CHF, alcohol
wandering pacemaker normal; often seen in very old, very young, athletes, persistence of junctional rhythm can indicate heart disease
premature atrial complex irregular pulse, rarely causes symptoms
wandering pacemaker rarely causes symptoms
atrial tachycardia very dangerous in AMI or heart disease, commonly caused by dig-toxicity
atrial tachycardia rapid regular pulse, may show signs/symptoms of drop in cardiac out put, can cause pulmonary edema, CHF, shock
atrial flutter rapid ventr. rate, loss of atrial kick can drop cardiac output, risk of pulmon, & cardiac emboli, can CHF or myocardial ischemia, seen in CAD, rheumatic heart disease
atrial flutter pulse can be regular or not, fast or slow, rapid ventr. rate can cause signs/symptoms of low cardiac output
