Check heart rate variability in sleep apnea heart rate monitor

Sleep apnea heart rate monitor is called holter monitor. During at night just using a holter monitor, sleep apnea disease can be diagnosed simply. Sleep disorder breathing is sleep apnea syndrome that is very common. This syndrome find in coronary heart disease or hypertension patient. Unfortunately, sleep apnea is not easy to diagnose and it has been estimated that 80-90% of all cases are not diagnosed. This is clearly a harmful problem because sleep apnea is connected with heart attack, stroke, angina, ventricular arrhythmia, hypertension, and lack of variability in heart rate. The obstructed sleep pattern is characterized sleep apnea As a result; it can increase the risk of accidents, depression, anxiety, memory loss and less sexual ability. The diagnosis needs to stay in the sleep-test lab overnight, where the patient is hooked to a Polysomonograph during sleep. Polysomonograph records such variables in the form of brain waves, eye movements, muscular activity, heart rate, and blood oxygen levels. Some devices also produce indications of snoring.

Researchers of Washington university school of medicine have given a proposal that relatively sleep apnea heart rate monitor (holter monitor) may be useful as a screening apparatus for sleep apnea. So friends come and let’s know about heart rate variability.

Obstructive sleep apnea (OSA) shows the cyclic difference of heart rate during eponymous time. We have estimated that autonomous changes will affect the frequency-domain measure of heart rate variability (HRV).

We examined 20 patients (15 men, 5 ladies, mean age 47.2 +/ – 12.2 years) with suspected OSA experiencing overnight polysomnography, and five patients (4 men, 1 lady, mean age 49.2 +/ – 8.6 years) with as of late analyzed rest apnea experiencing polysomnography while wearing persistent positive aviation route weight (CPAP). Holter screens were connected amid rest studies and information were broke down in 5-minute squares through the span of the night. Utilizing otherworldly examination, low recurrence (LF) and high recurrence (HF) powers were figured for every interim. General mean and standard deviation (SD) for LF control, HF control, and the LF: HF proportion was recorded for every patient. Correlations were made between patients with serious OSA (apnea hypopnea list (AHI) > 30, n = 8), direct OSA (AHI 1-30, n = 5), without OSA (AHI < 10, n = 7), and patients wearing CPAP (n = 5).

Overnight LF or HF power assessment does not show any significant difference between the four groups. LF: The HF ratio, which represents sympathetic balance, was higher among the mediated diseases than those mediates that were with severe OSA (both P = 0.037). Standard Deviation of LF: There was more between those with the moderate disease than those with HF ratio normals (P = 0.0064) and severe OSA (P = 0.0006). CPAP obtained OSA patients treated patients with moderate OSA, in which LF increased SD: HF ratio.

Changes in the LF: HF ratio and its SD have suggested a sympathetic tone and inequality in sympathetic activity in the moderate OSA, which is bloated in intense OSA. CPAP autonomic defects, characterized by severe OSA, can restore middle levels.

So friends if any patient which has sleep apnea than sleep apnea heart rate monitor is very useful for checking patient’s heart rate variability. During checking heart rate variability, patient is hooked with sleep apnea monitor for overnight. After the overnight, holter monitor gives their result as a heart rate graphs same as wave. After receive the holter monitor result, doctors begin treatment than make possibilities of patient diagnosed. Many patient get benefit with the sleep apnea heart rate monitor.
