Heart rate variability and fatty acid content of blood cell membranes: a dose-response study with n−3 fatty acids
sudden cardiac death cardiac arrest ventricular arrhythmias
2016/6/1
Dietary intake of long-chain n23 polyunsaturated
fatty acids (PUFA) may protect against sudden cardiac
death, an event that may be predicted by measurement of heart
rate variability (HRV).
Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the...
