PR interval

(redirected from PQ interval)

PR in·ter·val

in the electrocardiogram, the time elapsing between the beginning of the P wave and the beginning of the next QRS complex; it corresponds to the a-c interval of the venous pulse and is normally 0.12-0.20 sec.
Synonym(s): PQ interval

The outcomes of interest were HR, QTc, Tamp, PQ interval, ST-segment changes, and ventricular and supraventricular ectopic beats.
HR, QTc, Tamp, and PQ interval were not correlated according to the median of patient-specific Spearman correlation coefficients (data not shown).
We observed no significant associations between air pollutants and HR (Table 3) or PQ interval (data not shown).
Additional key features include: high-rate stimulation (up to 1000 ppm) delivered either as a programmable burst-set or as continuous pacing; back-up pacing during intrinsic sensing evaluations; PP and PQ interval measurements; and an user-defined program which is customizable to individual preferences in testing protocols.
