Palpitation
see also: Etymology of Palpitation
A Palpitation or palpitations corresponds to the fact of feeling its own cardiac beats in an unpleasant way (of the faster beats cardiac, stronger or irregular). The episodes can last of a few seconds to several hours, be daily or rarer. They can be well or badly tolerated. If they are associated with physical signs like a Malaise or a thoracic Douleur, an exploration is necessary.
Diagnosis
Important components to be noted
- Description of the felt symptoms:
- isolated Beats: Extrasystole S, auriculo-ventricular Block of the type II
- fast Beats: Tachycardia (regular or not)
- full Beats: Bigéminisme, auriculo-ventricular Block, arrhythmia (whatever is the cause)
- Circonstances of occurred: with the effort or rest, the day or the night, at the time of the catch of exciting
Diagnostic step
- By a complete and in particular cardiovascular clinical examination (search of a arterial Hypertension, a valvulopathy…)
- ECG : seek turbid rate/rhythm asymptomatic, of Extrasystole S auricular or extrasystoleventriculaires, of auricular Fibrillation, a Syndrome of Wolf-Parkinson-White, of a space short PR, after-effects of Myocardial infarction, turbid of cardiac conduction
- echography: seek of a cardiovascular disease ignored up to that point
- Holter-ECG
- + electrophysiological Explorations
Etiologies
Rhythmic causes
- turbid of conduction
- turbid of the rate/rhythm
Nonrhythmic causes
- psychiatric Context or psychological: stress, distresses, excitation, strong emotion
- Any disease involving a sinusal Tachycardie: Cardiac failure, Hyperthyroïdie, Anemia, Hypoglycemia, even Hyperthermia
- Toxicological with alcohol or another drug
External bond
- Orientation diagnoses at a patient presenting of palpitations
