Treatment of sinus tachycardia with heart-rate feedback.
A 23-year-old male with a history of sinus tachycardia was treated with heart-rate feedback in eight sessions. From a pretreatment average of 103 beats per minute (BPM) as recorded in two separate baseline sessions, the heart rate dropped to 66 BPM in the last treatment session. At follow-up the heart rate seemed stabilized within the normal range, averaging 68 BPM after 1 month and 73 BPM after 12 months. Simultaneous EMG recordings of m. frontalis suggest a generalized effect of this treatment. Results are discussed in terms of somatic and respiratory mediation.
