Our data indicate PAD alters the HRV in cardiovascular patients. PAD should be considered in the assessment of cardiac autonomic regulation especially in risk stratification.

Figure 4. Postextrasystolic regulation patterns (mean deviation from reference for each group) of the systolic BP (SBP, grey line) and the heart rate (HR, black line) in controls (top) and IDC patients (bottom) In controls, a typical baroreflex response was apparent, whereas in IDC patients, the baroreflex response was abolished due to the pronounced postextrasystolic potentiation (PESP).

The start of an increase in P wave size does not correspond with the entrance of the right atrium. The anatomic equivalent for the electrophysiological changes of the ECG is the pericardial reflection. ECG guidance is unable to distinguish between venous and arterial catheter position.
