Péricardite
|
diminution voltage en précordial (ép péricardique)
élévation ST et inversion T diffuse (myocardite) dépression PR diffuse Stage 1 – widespread STE and PR depression with reciprocal changes in aVR (occurs during the first two weeks) Stage 2 – normalization of ST changes; generalized T wave flattening (1 to 3 weeks) Stage 3– Flattened T waves become inverted (3 to several weeks) Stage 4 – ECG returns to normal (several weeks onwards) |

Syndrome du long QT

QTc>440
torsade de pointe alternance ondes T notched T waves dans 3 dérivations ondes U proéminentes |

|
WPW
|
PR interval <120ms
Delta wave – slurring slow rise of initial portion of the QRS QRS prolongation >110ms ST Segment and T wave discordant changes – i.e. in the opposite direction to the major component of the QRS complex Pseudo-infarction pattern can be seen in up to 70% of patients – due to negatively deflected delta waves in the inferior / anterior leads (“pseudo-Q waves”), or as a prominent R wave in V1-3 (mimicking posterior infarction). |

|
Wellen's syndrome
|
- Type A Wellens’ T-waves are deeply and symmetrically inverted en V2-V4
- Type B Wellens’ T-waves are biphasic, with the initial deflection positive and the terminal deflection negative en V1-V3 |

|
|
Hypokaliémie
|
- Increased amplitude and width of the P wave
- Prolongation of the PR interval - T wave flattening and inversion - ST depression - Prominent U waves (best seen in the precordial leads) - Apparent long QT interval due to fusion of the T and U waves (= long QU interval) |
|
|
Hyperkaliémie
|
- Peaked T waves (usually the earliest sign of hyperkalaemia)
- P wave widens and flattens - PR segment lengthens - P waves eventually disappear - Prolonged QRS interval with bizarre QRS morphology - High-grade AV block with slow junctional and ventricular escape rhythms - Any kind of conduction block (bundle branch blocks, fascicular blocks) - Sinus bradycardia or slow AF - Development of a sine wave appearance (a pre-terminal rhythm) - Asystole - Ventricular fibrillation - PEA with bizarre, wide complex rhythm |
