ECGs by diagnosis: Difference between revisions

Latest revision as of 05:31, 22 March 2026

ACS

See ACS

Aneurysm

see Left ventricular aneurysm

Suggested by:
- ST elevation >4wk
- QS wave in setting of ST-segment elevation with out T-wave inversion

Pericarditis

See [[Pericarditis*ECG|Pericarditis]]

Electrolyte Disorders

CNS

SAH, IC Bleed, CVA
- Diffuse wide, deep, blunted, inverted T waves
- QT Prolongation

Pacemakers

see Pacemaker complication

Should be in the apex of right ventricle
ECG should mimic LBBB with LAD

Pulmonary Embolism

see Pulmonary embolism

Sinus tachycardia
S1Q3T3 (Sp, not Sn)
Right axis deviation
RBBB
T wave inversions leads V1-V3

Hypothermia

Osborn wave (J wave) - Positive deflection at the J point
- Height of the J wave correlates to the degree of hypothermia^[1]
Bradyarrhythmias, AV blocks
Prolonged PR, QRS, QT intervals
Shivering artifact

-==Background==
+==ACS==
-#Poor R wave progression: no r's by V4
+''See [[ACS]]''
-==STEMI==
-#Posterior
-##ST depression in V1-V2
-##R-S ratio of >1 in V1 or V2
-##ST elevation >1 in V7-9
-##Often accompanied by inferior ST changes
-##Often accompanied by RV MI
-#Anterior
-##ST depression in II, III, aVF usually due to high lateral ST elevation (I, aVL)
-#Inferior
-##Look at I, aVL for reciprocal changes (ST depression or TWI)
-###If no changes pt probably not having an inf STEMI

-#7.0-8.0 -> QRS widens, slurred initial and term QRS, ST elevation, low wide P's, AV blocks, SA arrest, bradycardia.

-===Hypokalemia===
-#3.0-3.5 no change or flat T' sand U's in V2-3, QT interval and QRS nml.
-#2.7-3.0 U taller, T smaller, esp. V2-3
-#<2.6 ECG change includes tall U's, QT and QRS wnl.
-===Hypercalcemia===
-#Increased QRS duration (slight)
-#ST short or absent
-#Short corrected QT.
-#PR long
-===Hypocalcemia===
-#slight decrease in QRS.
-#ST and corrected QT long
-#PR short.
-#T's flat to inverted.

-#SAH, IC bleed, stroke, can see diffuse wide deep, blunted inverted T's. and QT prolonged
