HR: 100-150 bpm
Rhythm: Regular
QRS: Narrow
Treatment for Sinus Tachycardia
Determine underlying cause: Stress, Excercise, Caffeine, Anxiety, Infection, Hypoxic, Hypovolemia, Anemia, Decreased oxygen
Beta blockers, CCB
Supraventricular Tachycardia (SVT)
HR: Greater than 150 bpm
Rhythm; Regular
QRS: Narrow
Treatment for SVT
Stable person: Vagal Maneuver, BB, CCB, Adenosine( Need crash cart, Push fast, 6 mg, 12 Mg, 10 mL NS), Ditalizam
Unstable person: Synchronized Cardioversion, Ablation
Atrial FLutter
Rhythm: Regular
Flutter waves precedes each QRS
Saw tooth or picket fence apperance
Treatment for Atrial Flutter Stable person
Determine how long they have been in it( If 48 hrs risk for clots)
TEE (Transesophageal Echo)
Give blood thinners 4-6 weeks
Synchronized cardioversion
Sent home on Amiodarone
Treatment for Atrial flutter Unstable person
Synchronized cardioversion
May give CCB, Beta blocker
Anti-coagulant, BB, CCB, Amiodarone, Digoxin (If rhythm is controlled)
Atrial fibrillation
Rhythm: Irregularly Irregular
No identifiable P or T waves
P wave replaced by fine, chaotic waves
Treatment for Atrial Fibrillation for Stable person
Determine how long they have been in it ( if 48 hrs high risk for clots)
TEE
Give blood thinners 4-6 weeks
Synchronized cardioversion
Sent home on Amiodarone
Treatment for Atrial Fibrillation For Unstable Person
Synchronized cardioversion
May give BB, CCB
Anti-coagulant, BB, CCB, Digoxin, Amiodarone ( If rhythm is controlled)
First degree Heart Block
PR interval is greater than 0.2 sec and consistent
Treatment for First degree Heart Block
Pacemaker, Atropine
Second Degree AV BLock Type 1 ( Wenckebach)
Longer, Longer, Longer drop
PR intervals get longer than drop
Treatment for Second Degree AV Block Type 1 ( Wenckebach)
Pacemaker, Atropine
Second Degree AV Block Type 2 (Mobitz 2)
PR interval is consistent until QRS is dropped
Have some Ps that don’t get through
Treatment for Second Degree AV Block Type 2 (Mobitz 2)
Pacemaker, Monitor, Atropine
Third degree AV Block
Atria and Ventricles beat independently
If A and V don’t agree
Treatment for Third Degree AV Block
