kammiotakykardia
Kammiotakykardia is the Finnish term for ventricular tachycardia, a fast heart rhythm that originates in the ventricles. It is defined as a tachycardia with a rate typically between 100 and 250 beats per minute and a wide QRS complex on the surface ECG. Sustained ventricular tachycardia lasts at least 30 seconds or causes hemodynamic instability; non-sustained VT is shorter and may be self-limited.
VT is classified by QRS morphology into monomorphic VT, with a uniform QRS shape, and polymorphic VT,
Common causes include ischemic heart disease and prior myocardial infarction with scar tissue, cardiomyopathies, electrolyte disturbances
Clinically, patients may experience palpitations, dizziness, chest pain, or syncope. In unstable VT, there may be
Diagnosis relies on the ECG showing a wide-complex tachycardia. Further evaluation may include echocardiography to assess
Management depends on stability. In hemodynamically unstable VT, immediate synchronized cardioversion is indicated. In stable monomorphic
Prognosis varies with the underlying heart condition and VT burden. Kammiotakykardia signals an elevated risk of
