- Unstable pt= pt presenting w/ any S/S of CNS, CVS, or respiratory system (eg chest pain, shortness of breath, hypotension, or confusion) .
-1st step in ALL palpable ventricular arrythmia is Synchronized Defibrillation
- Epinephrin(IV) in 1:10,000 is for Rx. of heart rate and blood pressure.
- Epinephrin(SC) in 1:1000 of inhaled is used to Rx. Anaphylaxis respiratory distress.
Tachycardia>100
"QRS" complex is wide=MORE than 0.12 sec.= VENTRIVCULAR pathology
No palpable Pulse, No breathing=Dead Pt.!
Hx. of lightning or electrical injury
Asystole = flat line EKG Rx. I.Epinephrine, II.Atropine, III.transcutaneous pacing
Pulseless Electrical activity=normal EKG
Ventricular fibrilation
Rx. 1st: unsynchronized defibrillation(x3) 2nd: II.Epinephrine OR vasopressin , III.Defibrilate. IV.intubate, V.Defibrilate, VI.Amioderone or lidocain, VII. Procainamide Ejection fraction less then 35% OR positive arrhythmia induction on electro-physiology study Rx. Automated Implantable Cardiac Defibrillator
Ventricular tachycardia can present dead or Alive with a palpable pulse= HR is 120 or more & 3 ventricular beats or more
Dead Pt. Alive w/ palpable pulse UNStable Rx. 1st: Synchronized defibrillation stable Rx. I. Amioderon, II.Lidocain, III.Procainamide Long term Rx. for V.Tach is I. Beta-Blocker,II.AICD
Palpable pulse = pt. is alive and breathing
Hx. Heart Block, lithium, TCA, Porcainamide, a/w sudden audiatory of visual sti(eg : phone ringing)
Torsade de Pontes=EKG with elevation of "QT" Stable Rx.MgSo4 Unstable Rx.Unsynchronized defibrillation
Hx. Atrial Arrhythmia (Epstein anomaly), trans-position of the great vessels, S/S: loud S1
EKG= sluffed upstroke "QRS" deflection aka "Delta"-waves & short "PR' less than 0.12 sec. Dx. WPW= Wolff-Parkenson White Synd. Rx.Short term: Procainamide; Long term: Ablation
any "QRS" complex is narrow = LESS than 0.12 sec. is a/w ATRIAL pathology
IRREGULAR PULSE
Hx. Respiratory Disease
EKG= "P' wave has varying forms, a/w COPD & Resp. Failure Dx. Multi-focal Atrial Tachycardia Rx. the Respiratory disease will Rx. the arrhythmia
EKG= 350 to 500 ATRIAL beats, May have some "QRS" that are more than 0.12s
Dx. Atrial Fibrilation both atrial Fibrillation & Flutter have the same Rx. Acute Unstable Rx. Synchronized shock Stable Hx. Migraine, or CVS, or thyroid disease, Rx. Beta-Blocker= Propanolol (PO) Hx. depression, COPD, or asthma Rx. Ca-Channel Blocker Hx. low or boarder line blood pressure Rx. Digoxin Chronic is atrial arrhythmia for 2 or more days less than 60 y. of age Rx. Asprin more than 60 y of age Rx. Warfarin LONG term Rx is Cardiac Ablation
REGULAR PULSE
EKG=240 to 300 Atrial beat, "P" wave is saw tooth- shaped, 2:1 Atrio-Ventricular block
Dx. Atrial Flutter
EKG= 130 to 220 that SUDDENLY starts & Stops
Dx. Supraventricular Tachycardia Rx. Chronic Acute I. Vagal Stimulation maneuvers
II. Adenosin x 3
III. Same as the Rx. of an Acute stable pt with atrial fibrillation or flutter.
Bradycardia<60
EKG=constant "R-R" w/ SUDDEN dropped "QRS"
S/S Canon "a" wave on JVP
Rx. 1st: Atropin
2nd Pacemaker(IV)
ANY type of bradycardia S/S on P/E (eg palpable bradycardia with SOB or pain) = Must be treated
