All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Non-invasive technologies support the principles of 3Rs by enabling repeated data collection from the same animal without the need for euthanasia at multiple time points. These approaches reduce the number of animals required...

Listeria monocytogenes causes fetal infections in pregnant women and meningitis in susceptible populations. Subpopulations of bacteria can colonize cardiac tissue, causing myocarditis in patients and laboratory animals. Here we present a protocol that describes how to assess L. monocytogenes cardiac cell invasion in vitro and cardiac colonization in infected animals.

The aim is to promote a new approach to cardiac rehabilitation (CR), using a unique remote patient monitoring system that will enable healthcare providers to monitor CR patients at home at low cost, with the intention of making CR services more accessible and improving compliance. The study is currently underway.
FAQs
Each modality measures a different physiological signal. Electrocardiographic electrodes record cardiac electrical activity, photoplethysmography sensors detect changes in blood volume, cuffs measure arterial pressure, and ultrasound systems assess cardiac motion. Because these signals represent different aspects of cardiovascular function, selecting a modality depends on whether evaluation focuses on rhythm, circulation, pressure, or movement of the heart.
Recorded signals require clinical or algorithmic analysis to become meaningful cardiovascular information. Interpretation can characterize heart rate, rhythm, electrical activity, circulation, and related physiological changes rather than simply producing a numerical reading. This analytical step supports recognition of arrhythmias, assessment of cardiovascular status, and evaluation of whether a patient’s condition changes over time.
Electrical measurements and circulation-related measurements describe different physiological events. Electrocardiographic recordings reflect the heart’s electrical activity, while photoplethysmography detects blood-volume changes and blood-pressure cuffs measure arterial pressure. Ultrasound contributes information about cardiac motion. Comparing these measurement types helps clinicians and algorithms examine cardiovascular function from complementary perspectives instead of relying on a single signal.
A typical workflow begins by selecting an external device that matches the clinical question, such as electrodes for electrical activity, a photoplethysmography sensor for blood-volume changes, a cuff for arterial pressure, or ultrasound for cardiac motion. The device then records physiological signals, which clinicians or algorithms analyze to characterize function and identify relevant changes.
Clinicians may use these approaches to identify arrhythmias, track physiological changes, and evaluate responses to treatment. Their external design supports repeatable assessment with low procedural risk, making them useful when cardiovascular information must be collected more than once or followed over time. The same capabilities can support evaluation both during clinical care and beyond the hospital.
Wearable sensors and other external devices can extend cardiovascular observation beyond a hospital visit. Repeated or continuing measurements support long-term health surveillance and can reveal physiological changes that inform individualized cardiovascular management. In medicine, this accessibility also helps connect monitoring with remote care, while the low procedural risk makes ongoing assessment more practical.
