A 28 yom is evaluated for palpitations. He reports a 5 year history of
palpitations. These episodes used to occur once or twice a year, but over the
past 6 months, he has been experiencing them on a monthly basis. He reports
that his heart starts racing suddenly for no reason, and the episode usually
terminates abruptly after he takes a few deep breaths. Episodes typically last 10
to 15 minutes, although one episode last month lasted 30 minutes. He is
otherwise healthy, denies other symptoms, and takes no medications. Results of
his physical examination are within normal limits. A baseline EKG is obtained
and shown. The ECHO demonstrated a subtle anterior wall motion abnormality
but is otherwise WNL. A 24 hr holter demonstrates a narrow complex regular
tachycardia with rate of 205 during an episode of palpitations.
What is the next step?
RF ablation
metoprolol

tachycardia with rate of 205 during an episode of palpitations.
What is the next step?
RF ablation
metoprolol
stress test
verapamil
WPW

Short PR interval +delta wave +h/o tachycardia = WPW

Two circuits:
1.
2.
AV node
retrograde accessory pathway

QRS in narrow since there is conduction via AV node

The WMA is a result of abnormal depolarization via the accessory pathway.

RF ablation is first line

Avoid metoprolol, CCB, and adenosine; they blocks the AV node but not
the accessory.

Use Procainamide
A 45 yof is evaluated in the emergency department for
palpitations. She has no history of CV disease but does have a h/o
intermittent palpitations. This is her first prolonged episode, and
cough and strain maneuvers that she has used in the past to terminate
the episodes have been ineffective this time. PE is unremarkable
with the exception of tachycardia. The BP is 110/70. EKG shown.
What is the diagnosis:
AV nodal reentrant tachycardia
AV reentrant tachycardia
ectopic atrial tachycardia
multifocal atrial tachycardia
a flutter

Look for drug effect (dig, beta blocker, CCB)
Mobitz I: PR progressively lengthens, then a dropped beat

Atypical Vtach
Look for hypoK or hypoMg
Worse prognosis than V tach
Management is different from other VTs

Avoid Class I, Ic or III antiarrhythmics (prolong QT)
Give Magnesium acutely
Things that cause torsades: arsenic, ciapride,
droperidol, Li, methadone, fluoroquinolones
A 79 yof is seen for an annual examination. She is in good health except for osteopenia, for
which she takes Ca and VitD supplements. She walks regularly to and from the bus stop
several times per week. It now takes her 25 min to get to the bus stop; whereas it only took her
10 min a year ago. She describes dyspnea midway in her walk, causing her to stop and catch
her breath. She denies angina, presyncope, syncope or pedal edema. PE: HR 80, BP 165/86.

Ascending vs Descending
Ascending dissections are high risk for complications.
Do not pass go, instead… go directly to surgery.
Descending dissections treat medically (Beta Blockers
and nitroprusside-if needed), and if pain persists, it is
due to extension of dissection, then go to surgery.
Even with repair mortality is 26%, without 55%

Post-MI complications
1. Recurrent ischemia: 1/3 of patients, and more common in NSTEMI
rather than STEMI.
2. Arrhythmias: bradycardia, SVT/atrial fibrillation, ventricular
arrhythmias (mostly in the first few hours), AV block,
3. CHF
4. Myocardial rupture: rupture of the LV, 1% of pts, 2-7 days
(pseudoaneurysm- rupture sealed by pericardium)
5. LV aneursym: from scar, predisposed to CHF, thrombus, and
arrhythmias
6. Papillary muscle rupture: posteromedial papillary muscle is more
common b/c single blood supply from RCA. Classic case: inferior MI,
later becomes hypotensive, large V waves in PA wedge tracing, new
holosytolic murmur at the apex.
7. Mural thrombi (in anterior and apical STEMI)

Treatment of HTN benefits are greater in the older
patients compared to young patients. Reduces CVA,
CHF and CV events, but not overall mortality
Isolated systolic HTN is still high risk, even in the
elderly, and should be treated.
Wide pulse pressure is a risk factor for CHF.

Stage 1: 140-159/90-99
Stage II: >160/100
Goal: treat to < 140/90 or <130/80 if DM
Always start with a thiazide unless Post MI or CKD
 The number one reason for failure to control hypertension despite
multiple agents is the failure to use a thiazide diuretic.
CHF: thiazide, BB, ACEI, ARB, spironolactone
POST MI: BB, ACEI, spironolactone
DM: thiazide, BB< ACEI, ARB, CCB
CKD: ACEI, ARB
Recurrent CVA: thiazide, ACEI
High CVD risk: thiazide, BB, ACEI, CCB
