In this clinical study the investigators will evaluate if it is feasible to pre-operatively identify low-risk patients, and to identify patients with cardiac pathologies with the LynxPatch.

The LynxPatch is a non-invasive, wireless device for cardiac diagnosis. The aim of this study is to compare the LynxPatch predictions with the echocardiographic diagnoses of cardiac pathologies and to evaluate its perioperative risk predictions in non-cardiac surgeries. The study population includes 1100 patients that scheduled for an echocardiographic assessment or for a non-cardiac surgery. The LynxPatch measurement procedure has a duration of about 30 minutes.

Inclusion Criteria:

• Provision of informed consent, i.e., the subject must be able to understand and sign the Patient Information and Consent Form.
• Group 1: Patients that have an indication for an echocardiographic assessment.
• Group 2: Patients that are scheduled for a non-cardiac surgery

Exclusion Criteria:

• Subjects has implanted cardioverter defibrillator
• Subject is pregnant
• Subject is breastfeeding
• Subject has compromised skin in the location where the LynxPatch is intended to be positioned

In this study, all patients will be consecutively recruited that are either scheduled for an echocardiographic examination or that will be subjected to a non-cardiac surgical procedure according to their respective standard procedure.
