To all those who watch TV and do breathing/pranayama just by watching TV. Kapalbhati and Bhastrika are EXTREMELY powerful techniques and leave a profound impact on our mind and the body.
At the same time, these 2 practices also have a very strong effect on our Autonomic Nervous System (via heart rate changes).
If you have Diabetes or Hypertension, please do NOT do any Kapalbhati or Bhastrika practices without seeking the guidance of qualified yoga teacher.
There are many other practices you can do but NO to Kapalbhati and Bhastrika (especially with above 2 disorders). The visual shows heart rate variability during kapalbhati vs chanting. Not just the heart rate varies very well during chanting. Any variation in Heart Rate is a good sign and it helps you calm the mind and emotions !).

One more view of how Kapalbhati increases the heart rate (in Yellow) and decreases the HRV (in Red) from 18:43:30 to about 18:44:30. Normal breathing after Kapalbhai (till 18:45:30) restores HRV to some extent. Bhramari Chanting followed by slow breathing (in the 2nd half) demonstrates that during chanting the HRV shows an improvement.
