Statistical analysis of RR and PR ECG intervals

Conditions	RR/PR
	Girk4^−/−_NaCl	WT_Atrop	Girk4^−/−_Atrop	WT_Prop	Girk4^−/−_Prop
WT_NaCl	NS/NS	<0.05/NS	<0.01/<0.05	<0.01/NS	<0.001/NS
Girk4^−/−_NaCl		NS/NS	<0.05/NS	<0.001/NS	<0.001/<0.01
WT_Atrop			NS/NS	<0.001/<0.01	<0.001/<0.001

WT_Prop					NS/NS

Atrop, atropine; Prop, propranolol. ECG interval values in WT and Girk4^−/− mice under control conditions (intraperitoneal injection of NaCl) or after systemic administration of 0.5 mg/kg atropine or 5 mg/kg propranolol are shown.
