  Figure 2. Schematic displaying the potential role of the mobile application, photoplethysmography, and patient involvement in the case of an arrhythmia. ATP = antitachycardia pacing; ICD = implantable cardioverter-defibrillator; PPG = photoplethysmography; (S)VT = (supra)ventricular tachycardia.

  Figure 3. Several types of arrhythmias as detected by the implantable cardioverter-defibrillator and the arterial blood pressure as measured by photoplethysmography. ECG = electrocardiography; HS = hemodynamically stable; HU = hemodynamically unstable; PPG = photoplethysmography; SVT = supraventricular tachycardia; VT = ventricular tachycardia.
