EBM guidelines for treating hypertension
- People >60, goal for SBP is <150, DBP <90
- People <60, SBP <140, DBP <90
- People >18 w/ CKD <140/90
- People >18 w/ diabetes <140/90
In the general non black population, initial antihypertensive tx should include:
A thiazide diuretic
Ca channel blocker
ACE inhibitor
Or Angiotensin Receptor Blocker
In the general black population, initial antihypertensive tx should include:
Thiazide diuretic or Ca channel blocker
Tx for people >18 w/ CKD and HTN
ACE inhibitor or ARB to improve kidney outcomes
Asystole
> 3 sec sinus pause
Sick sinus syndrome
Asystole with symptoms
Intermittent absent P waves
2nd degree SA block
Lack of atrial activity, subsidiary ectopic atrial pacemaker, sinus arrest on ECG
3rd degree SA block
Slow sinus response to PACs
1st degree SA block
Sinus bradycardia vs. tachycardia
<60
>100
Dx and tx of SA node dysfunction
Dx: holter, event recorder, carotid sinus pressure pauses >5sec
Tx: ventricular pacer, AV ventricular pacing
AV blocks
2nd degree
Intermittent blocks.
A. Mobitz I (wenkebach): normal QRS, 3:2, 4:3, 5:4 (PR longer longer, longer, drop)-inferior MI, His abnormality, drugs
B. Mobitz II: infra His, wide QRS 2:1, 3:1, 4:1 (PR uniformly long, then drops)
Normal PR
0.12-0.2 seconds
Tx of bradyarrhythmias
Atropine
Pacemakers
____ can’t be seen on an ECG
1st degree SA block
