Q

Paroxysmal ventricular tachycardia?

A

نبضات في البطين متتالية مش طبيعية مفيش بينهانبضة واحدة طبيبيعة ياعمر !
عشان ؟
ventricular ectopic focus
re-entrt
norma atrial impulses
ventricle : 150-200 casuing diastolic dysfunction

ECG? absent p , slurred notches QRS , Inverted T
Treatment :;Cardioversion

16
Q

The ventricular fibrillation is due to ?

A

ischemia
electric shock
or
Ectopic foci in the vulnerable period?

17
Q

Vunerable period?

A

period in midtime of repolariztion T wave :
Some fibers depeolarized some incompletelty reploarized some repolarized
stimulation of fibers there casueing reentry phenomenon and ectopic focus develops

18
Q

Ventruclar fibrillation chracteristics?

A 
Absent coordinated beat
No pulse
No cardiac Output
ECG: Undulating waves
Treatment: Cardioversion 2500-3000
19
Q

Wolf parkinson shite syndrome ?

A

presnce of accessory bundle of kent between the artium and ventricule
there are two types of conduction ? ]
Through kent: bypass the delay of the AVN and casuing short pr and slow cell to cell deplarziation of the ventricle
Through AVN With the delay and ventrcular REMAINDER OF QRS
Delta WAVE

20
Q

Wolf parkinson white syndrome and ecg ?

A

Normal P wave
Short PR
Prolonged QRS slurred on upstroke Delta wave

21
Q

AV block casuses?

A

Ischemia to AVN OR BUNDLES
Septal infarction
Compression of avn or bundles by scar
Damage to the AVN or bundles during surgical interventricular septal defect
Myocarditis damagin avn diptheria rhematic fever

22
Q

1st and snd degree heart block ?

A

1ST : Prolonged pr interval no drop
2nd : P:QRS 2:1 3:1 drop
Wenekebach phenomenon ?
Prlongation of the pr interval till the drop the recycles

23
Q

Complete heart block ?

A

Complete dissociation between the atria and venricles

24
Q

Bundle branch block BBB ?

A

the impulse pass through intact bundle then to the other ventricle by cell to cell conduction and
this leads to axis deviation
prolonged QRS with 2peak
inverted T wave

25
Q

Coronary artery occlusin and ECG ?

A

ST segment elevation
T wave inversion
Deep Q

26
Q

Hypokalemia ECG” ?

A

prolonged PR
LOW INVERTED T WAVE
U WAVE PROMINENT

27
Q

Hyperkalmeia lethal and ECG?

A

Tall peaked T Wave
AVN BLOCK
Ventricular fibrillation
