T/F
You are more likely to die from SVT than from Ventricular arrhythmias. |
FALSE
V. tach and V. fib is WAAAY more worrisome that SVT. |
|
|
what tx is available for ventricular ectopy?
|
none-->
B-blockers if the pt is significantly symptomatic avoid stimulants |
|
|
describe Ventricular tachycardia on EKG?
|
rate 120-180
wide QRS no p waves |
|
|
what are the clinical manifestations of V. tach?
|
profoundly symptomatic-drop in BP, chest pain, syncope, super sick
|
|
|
how do you tell the difference bwteen PAT and V tach?
|
PAT is narrow QRS, V tach is wide
|
|
|
what are the two types of V. tach? describe them. which one do we tx?
|
nonsustained: less than 30 beats- short bursts
sustained: greater than 30 beats- long bursts---> tx these people |
|
|
what are the sxs of V tach?
|
sometimes asymptomatic. associated lightheadedness, near syncope or syncope. Occasional anginal pain and dyspnea
|
|
|
how do you tx sustained V tach?
|
DC cardioversion is pt is profoundly symptomatic, antiarrhythmic, implantable defib, ablation
if pt has ischemic disease--> b-blocker is preffered |
|
|
what is one of the major causes of Ventricular arrhythmias?
|
ventricular scarring and CAD from heart attacks
|
|
|
describe V fib on EKG.
|
grossly irregular waveforms w/ varying morphology. Rate variable and very rapid. often unable to distinguish distinct QRS complexes.
|
|
|
what are the sxs of V fib?
|
sudden syncope and pulselessness, results in death unless converted.
|
|
|
how do you tx V fib?
|
ACLS protocol
implantable defibrillator is successfully resuscitated |
|
|
what is ACLS protocol?
|
DC cardioversion, precordial thump and chest compression, antiarrhythmic in sequence
|
