Zusammenfassung
Obwohl bildgebende Verfahren zur kardialen und Ischämiediagnostik zunehmend eingesetzt werden, bleibt das Belastungs-EKG der erste Schritt in der kardialen Diagnostik sowohl zum Ischämienachweis als auch zu Beurteilung von Funktion und Prognose. Die Methodik folgt standardisierten Empfehlungen (Leitlinien). Wichtigster Aspekt zur zuverlässigen Diagnostik ist die Ausbelastung des Probanden oder Patienten. Neuere Messgrößen erlauben eine zuverlässige individuelle Risikoabschätzung. Arrhythmien nach Belastungs-Ende liefern zusätzliche prognostische Aussagen. Leitlinien und Qualitätsrichtlinien werden noch zu selten beachtet.
Abstract
Cardiac imaging plays an increasing role in exercise testing. However, exercise testing with ECG remains a classical and basic approach to analyze cardiac function and to screen for coronary artery disease. Maximal testing, i. e., terminated by exhaustion of the patient, is important to achieve a reliable diagnostic result. New parameters have been introduced such as recovery heart rate, blood pressure and functional capacity. These parameters improve risk stratification, thus, increasing prognostic power of exercise testing. General and specific quality management has still to be improved in exercise testing.
