This was a case of a 57-year-old patient, whose dosage of a drug for treatment of essential thrombocythemia was increased. However, this increase began to trigger tachycardia. The patient described symptoms such as palpitations, chest pain and heart pain.
Already during the first days of monitoring by the episodic recorder, incoming records were evaluated as supraventricular extrasystoles, isolated and in volleys, which repeatedly progressed into paroxysms of non-sustained supraventricular tachycardia (Fig. 1) or to paroxysms of atrial fibrillation with fast ventricular response of up to 190/min (Fig. 2), always accompanied by the mentioned symptoms described by the patient.
Paroxysms were recorded several times per day and lasted from dozens of minutes up to 3 hours. The telemedicine centre sent notification about the ongoing monitoring to the patient’s attending doctor, who immediately invited the patient for a check-up. After adjustment of the medication, the sinus rhythm became sustainable during the next few days, which lasted until the end of monitoring (Fig. 3).
Patient: male, 57 years old
Specification of health complications: After an increase of drug dosage for treatment of essential thrombocythemia, the patient described symptoms such as palpitations, chest pain and heart pain.
Monitoring: episodic recorder
Result: Already during the first days of monitoring by the episodic recorder, incoming records were evaluated as supraventricular extrasystoles, isolated and in volleys, which repeatedly progressed into paroxysms of non-sustained supraventricular tachycardia or to paroxysms of atrial fibrillation with fast ventricular response of up to 190/min. After adjustment of the medication, the sinus rhythm became sustainable during the next few days, which lasted until the end of monitoring (Fig. 3).
