Murmur Detection

Visualize Heart Murmur

The CardioSleeve stethoscope attachment enhances a stethoscope by providing synchronized Digital Auscultation with ECG; allowing for visualized heart sound and Murmur Detection.


 

 

 

Murmur Detection

CardioSleeve adds advanced murmur detection technology to any standard stethoscope and provides:

 
  • Cardiac murmur assessment with more than 90% accuracy

  • Visualization at the time of examination

  • Recording and archiving of the findings

  • Comparison with a previously recorded murmur

  • Instant assurance for the patients

 

SEE WHAT YOU HEAR

Since the invention of the stethoscope by Laennec in 1816, many illustrious physicians have contributed to its development to improve the art of auscultation. They have only met with limited success on account of the limitation of human hearing.

The human ear can only perceive sounds between 20 and 20,000 Hz: it can neither reach beyond (as dolphins and whales do) nor go below it (as elephants often do). Yet, in this range, it has a preferential bandwidth of 1000–5000 Hz, corresponding to that of the human voice. Yet, most cardiac sounds are <500 Hz. In fact, many are so low pitched to be almost inaudible (S3 or S4 can be <100 Hz). Cardiac sounds are crammed in a very little time interval. At a rate of 70/minute, a cycle of 0.8 seconds can easily harbor four to five sounds, many barely detectable.

Even enhanced auscultation with the ‘state of the art’ modern stethoscope, the cardiac findings remain entirely subjective and user dependent. The incapability for accurate diagnosis is further compounded by time constraints, medico-legal issues (which have made imaging a self-protecting necessity), patients’ demands and expectations, and reduced emphasis on bedside skills during training. The shortcomings lead to an ever-increasing need for resorting to expensive technologies.

CardioSleeve transcends the limitation of human hearing and overcomes the inadequacies of the modern stethoscope. The audiovisual display overpowers the threshold of audibility and allows to measure the relative intensity of S1 and S2, visually verify split S2, amplify murmurs, and replay heart sounds at half speed for analysis. The integrated murmur detection software (with a 90% or more accuracy) aids in the diagnoses of pathological and physiological heart sounds even at heart rates of up to 180 bpm!

The timely and objective reliable results thus reduce unnecessary referrals and tests; provide legal protection, improve outcomes, and improve patient care experience making CardioSleeve an indispensable cost-effective tool for definitive diagnosis at any point of care.

 

Murmur Detection By Specialty

 

Family Physicians

Every day a Family Physician is faced with cardiac murmurs ranging from ‘physiologic’ in the young to the ‘pathologic’ in the elderly. With CardioSleeve, the assessment can be made with great confidence and need for an Echocardiogram eliminated for innocent murmurs.

Pediatricians

Evaluating cardiac murmurs in the pediatric population is always challenging. A restless patient, noisy environment and rapid heart rate make the examination quite difficult. CardioSleeve murmur detection software aids in the diagnoses of pathological and physiological heart sounds even at heart rates up to 180 bpm!

 

 

Dentists

Heart murmurs, a common finding in dental patients, are of major concern to dental professionals because certain dental procedures occasionally can induce severe cardiovascular complications. Murmurs may indicate existing heart disease that is a risk factor for infective endocarditis following a dental procedure.

 

 

Nurse Practitioners

Nurse Practitioners are playing an ever-bigger role in providing primary care services within their communities, either as part of a physician group or within retail clinics. With this expansion of services, the responsibility to deliver quality services is also growing. Murmur detection with CardioSleeve empowers them to screen patients with confidence.

Physician Assistants

A physician assistant may not feel comfortable in differentiating innocent from pathological murmurs while performing a physical examination on a patient. CardioSleeve, allows them to make an accurate decision before referring the patient to a physician.

Sports Screen

Cardiac related deaths on the sports field are a reality, even among fit athletes. A timely identification of murmur with CardioSleeve could well prevent sudden cardiac death.  

Occupational Medicine

A comprehensive cardiac assessment is vital for any employee. CardioSleeve is invaluable in detecting pathology during a pre-employment screen.   

Summer Camp Physicals

Every year a large number of children die due to cardiac related defects while attending a summer camp. Reliable assessment with the CardioSleeve is useful as part of a summer camp physical screening.
