Multiple Sleep Latency Study

Garry has returned following a repeat diagnostic sleep study combined with a multiple sleep latency test. The overnight study revealed a sleep latency of seven minutes with good sleep efficiency of 80%. Almost eight hours of sleep was recorded. Again there was no evidence of obstructive sleep apnoea or periodic limb movements. Oxygen saturation was slightly reduced during the first half of the study at around 90% but this improved to 95% during the latter pasts.

The ECG rhythm strip again revealed ST depression, however a 12-lead ECG has demonstrated a left bundle branch block.

Ihave suggested that Garry have his mandibular advancement splint adjusted to deal with the snoring, start exercising regularly to lose weight and he will also see Chris Goods in the next weeks.

WE may need to consider doing a repeat study with repeat latency test some time next year. Garry will give me a call once he has caught up with Chris
