Normal HRV
Normal Poincaré Plot
Has variability to react to the physiologic changes that the body is going through during sleep
Heart Rate Variability
• The Poincaré Plot◦ X-axis :: measure of the current RR interval◦ Y-axis :: measure of the next RR interval
Current RRn Interval
(x-axis)
Next RR Interval (RRn+1)(y-axis)
Bradycardia
- Normal Sinus Rhythm, where heart rate is below 60 bpm
- All of the points shift to the upper right
- Display’s INCREASED time between R-R intervals
Tachycardia
◦ All of the points shift to the lower left
◦ Display’s DECREASED time between R-R intervals
-“Dot” Pattern represents pacemaker-NO variability from the patient-Heart rate totally controlled by pacer
Pacemaker
On Demand Pacemaker
◦ Controlled Rhythm
◦ Not much variance
OSA – Brady/Tachy
• Typical Pattern for OSA patient◦ HR DECREASES during Apneic Event◦ HR INCREASES after Apneic Event
Decreased HR
Increased HR
Obstructive Sleep Apnea
“Fan” Pattern• Wide variations in R-wave
interval• Typical OSA Patient pattern• Data points vary from
Tachycardia (lower left corner) to Bradycardia (upper right corner)
