Periodic breathing, breathing irregularity, and apnea/hypopnea score in experimental CHF.

	Periodic; breathing	Breathing; irregularities	Apnea/hypopnea; index	References
MI-CHF	ND	↑	↑	[26]
RP-CHF	↑	↑	↑	[35]
AB-CHF	ND	ND	ND
G-CHF	ND	↑	↑	[41]
ACS-CHF	ND	ND	ND

ND: not described; ↑: increased; ↓: decreased; and —: without difference compared to control healthy condition. MI-CHF: myocardial infarct chronic heart failure; RP-CHF: rapid pacing chronic heart failure; AB-CHF: aortic banding chronic heart failure; G-CHF: genetic chronic heart failure; ACS-CHF: aortocaval shunt chronic heart failure.
