Arrhythmia Flashcards
Characters of normal sinus rhythm through p wave
_positive p wave in lead||
_negative p wave in aVR
Causes of sinus tachycardia
Increase sympathetic stimulation
Fever ex typhoid, diphtheria
Hyperthyroidism
Abnormal characters of sinus tachycardia
Short RR interval
Increase heart rate
Causes of sinus bradycardia
Increase vagal tone
Hypothyroidism
B blocker
Characters of sinus bradycardia
Decreased heart rate
Prolonged RR interval
Characters of respiratory sinus rhythm
R R interval is shortened during inspiration
And prolonged during expiration
Characters of AV nodal rhythm
AV node is pacemaker
Bradycardia
Inverted p wave
Short PR interval
Characters of supraventricular extra sytole
Inverted or absent p wave
Short PR interval
Incomplete compensatory pause
Resetting sA nodal rhythm
Characters of ventricular extra sytole
Absent p wave Wide bizarre QRS Inverted T wave Axis deviation Complete compensatory pause Not depolarize SA node As no retrograde conduction High voltage QRS
Why inverted T wave in ventricular extra sytole
As first area to depolarize is the first area to repolarize
Why high voltage QRS in ventricular extra sytole
As impulse travel in one direction
Why post extra sytole potentiaton
Dt long diastolic period
Increase ventricular filling
Treatment of atrial fibrillation…..
While treatment of ventricular fibrillation……
Paroxysmal ventricular tachycardia….
_cardioversion, digitalis, anticoagulant
_carduoversion2000:3000V
_cardioversion
Bag of worms in
Atrial fibrillation
Ventricular fibrillation
What is F wave
Irregular undulation of base line
In atrial fibrillation
Characters of ventricular tachycardia
No p wave Slurred,notched,wide QRS T wave opposite direction of QRS Filling, pumping,CO decreased Normal atrial rate
Wolf Parkinson white syndrome
Rapid atrioventricular conduction Accessory bundle, bundle of kent Delta wave Short PR interval Slurred prolonged QRS
What is delta wave
Slurred ascending limb of QRS in wolf Parkinson white syndrome
Short PR interval
AV nodal rhythm
Supraventricular extra sytole
Paroxysmal nodal tachycardia
Wolf Parkinson white syndrome
Prolonged pR interval
1st degree AVN block
Wenckebach phenomenon (2nd degree AVN block_mobtiz1)
Hypokalemia
Inverted p wave
AV nodal rhythm
Supraventricular extra sytole
Paroxysmal supraventricular tachycardia
Inverted T wave
Mild ischemia
Acute myocardial infarction
Hypokalemia
T wave opposite direction
Ventricular tachycardia
BBB
Pulsus dificit
Supraventricular extra sytole
Atrial fibrillation
Characters of hypokalemia
Prolonged pR interval
T wave inverted
Prominen U wave
Characters of hyperkalemia
Tall peaked T wave
AVN block
Ventricular fibrillation
Reentry phenomenon
Deep Q wave
Dead muscle
Old myocardial infarction
ST segment elevation
Myocardial infarction
Stock Adams syndrome
Cerebral ischemia
15:20bpm
P:QRS ratio is 2:1
