Gating currents associated with Na channels in canine cardiac Purkinje cells

Gating currents (Ig) were recorded in single canine cardiac Purkinje cells at 10-12 degrees C. Ig characteristics corresponded closely to macroscopic INa characteristics and appeared to exhibit little contamination from other voltage-gated channels. Charge density predicted by peak INa was 0.14-0.22 fC micron -2 and this compared well with the measured value of 0.19 +/- 0.10 fC micron -2 (SD; n...

Differences in ionic currents between canine myocardial and Purkinje cells

An electrophysiological analysis of canine single ventricular myocardial (VM) and Purkinje (P) cells was carried out by means of whole cell voltage clamp method. The following results in VM versus P cells were obtained. INa3 was present, had a threshold negative to the fast activating-inactivating INa1, its slow inactivation was cut off by INa1, and contributed to Na+ influx at INa1 threshold. ...

Cardiac Na currents and the inactivating, reopening, and waiting properties of single cardiac Na channels

Tetrodotoxin (TTX)-sensitive Na currents were examined in single dissociated ventricular myocytes from neonatal rats. Single channel and whole cell currents were measured using the patch-clamp method. The channel density was calculated as 2/micron 2, which agreed with our usual finding of four channels per membrane patch. At 20 degrees C, the single channel conductance was 20 pS. The open time ...

Kinetic analysis of single sodium channels from canine cardiac Purkinje cells

Single sodium channel events were recorded from cell-attached patches on single canine cardiac Purkinje cells at 10-13 degrees C. Data from four patches containing two to four channels and one patch with one channel were selected for quantitative analysis. The channels showed prominent reopening behavior at voltages near threshold, and the number of reopenings declined steeply with depolarizati...

Isolation and characterization of single canine cardiac purkinje cells.

Single cardiac Purkinje cells should permit improved control of membrane potential during voltage clamp studies. We have developed a method for isolation of single canine Purkinje cells and studied their basic electrophysiological properties using conventional single and double microelectrode techniques. The single Purkinje cells appeared free of connective tissue, had regular striations, exclu...
