heart rate

n. Abbr. HR

The number of heartbeats per unit of time, usually expressed as beats per minute.

---

heart rate,

the frequency with which the heart beats, calculated by counting the number of QRS complexes or ventricular beats per minute. See also pulse.

---

heart,

n the muscular pump that maintains and regulates the flow of blood through the body.

heart, artificial,

n a mechanical device that acts to pump blood to and from the body tissues during repair of the heart.

heart attack,

n See myocardial infarction; thrombosis, coronary; or occlusion, coronary.

heart block,

n the condition in which the muscular interconnection between the auricle and ventricle is interrupted so that the auricle and ventricle beat independently of each other.

heart, compression of,

n See massage, cardiac.

heart defect,

n a fault in the structural integrity of the heart.

heart defect, congenital,

n the structural errors in the heart formed during embryonic and fetal life.

heart disease,

n a disorder in the normal functioning of the heart.

heart disease, dental concerns,

n.pl the special considerations taken to eliminate oral disease by maintaining an elevated level of oral health and prevent infective endocarditis, an infection of the heart valves that may be caused by bacteremia created during dental treatments. Heart disease has also been linked with increased levels of periodontal disease.

heart disease, ischemic,

n See disease, heart, ischemic.

heart disease risk factors,

n.pl the hereditary, lifestyle, and environmental influences that increase one's chances of developing heart disease.

heart massage,

n See massage, cardiac.

heart murmur,

n the sound of blood flowing back through a defective heart valve. Two types are possible: organic or functional.

heart, normal,

n a heart without anatomic defects that could cause an impairment in the function of the organ.

heart rate,

n the rate or tempo of heart contractions recorded in beats per minute.

heart sounds,

n.pl the normal noises produced within the heart during the cardiac cycle that can be heard over the precordium and may reveal abnormalities in cardiac structure or function. The use of the stethoscope over the left side of the chest is a common clinical technique to assess heart function. The typical sounds are a rythmic lub dup; abnormal sounds include clicks, murmurs, rubs, snaps, and gallops.

heart surgery,

n a surgical procedure involving the heart, performed to correct acquired or congenital defects, to replace diseased valves, to open or bypass blocked vessels, or to graft a prosthesis or a transplant in place.

heart valves,

n.pl one of the four structures within the heart that prevent backflow of blood by opening and closing with each heartbeat. They include two semilunar valves, the aortic and pulmonary; the mitral, or bicuspid, valve; and the tricuspid valve. They permit the flow of blood in only one direction, and any one of the valves may become defective, permitting the backflow associated with heart murmurs.

rate,

n measurement of a thing by its ratio or given in relation to some standard.

rate, basal metabolic,

n See basal metabolic rate.

rate, DEF,

n an expression of dental caries experience in primary teeth. The DEF rate is calculated by adding the number of decayed primary teeth requiring filling (D), decayed primary teeth requiring extraction (E), and primary teeth successfully filled (F). Missing primary teeth are not included in the count because whether they were extracted because of caries or exfoliated normally is often impossible to determine.

rate, DMF index,

n a method of classifying the condition of the teeth based on the number of teeth in a given oral cavity that are decayed, missing, or indicated for removal and of those filled or bearing restorations.

rate, erythrocyte sedimentation

n the rate of settling of erythrocytes by gravity under conditions in which all factors affecting the rate are corrected, standardized, or eliminated except for alterations in the physicochemical properties of the plasma proteins. These alterations are the basis for interpretation of the rate. There is an increase in the rate in most infections. Sedimentation velocity is useful in prognosis to determine recovery from infection. Normal values vary with the method used in the determination.

rate, heart,

n the rate of the heartbeat, expressed as the number of beats per minute. The heart rate is reflected in the pulse rate. The cardiac rate of contraction is described as normal (70 beats/min), rapid (more than 100 beats/min), or slow (less than 55 beats/min). Disturbances in heart rate and rhythm may be paroxysmal or persistent. Descriptive terms are
tachycardia (increased, shallow heart rate to compensate for inadequate cardiac output) and
brady-cardia (slow, firm heart rate caused by cardiac sinus mechanisms and the vagal effect over the sympathetic innervation of the heart).

rate, survival,

n the percentage of survivals within a certain study; in dentistry, it refers to the percentage of implants that are functioning within acceptable standards.

Patient discussion about Heart rate (exercise).

Q. Why do people with a better cardiovascular fitness have lower heart rate? I recently met my old friend and that too after long time. We did go out and had a blast. He did show me his medical report and I was shocked to find out that he was having lower heart rate than me but was having better cardiovascular. He told me that it was quite normal but It was bothering me a lot. How could it be possible and I do see this as a deficiency. My friend does not agree with me and he told me that nothing to worry. I did try to research and found nothing with this regards. I am unable to sleep and would like to know on this. Can someone help me with answers?. Why do people with a better cardiovascular fitness have lower heart rate?

A. A strong athletic heart gets more cardiac output per stroke.
Less strokes = more movement of blood per stoke

Q. I had my blood test as I was feeling dizzy and my heart rate was raised & I was diagnosed with hyperthyroidism I had my blood test as I was feeling dizzy and my heart rate was raised & I was diagnosed with hyperthyroidism. It had just started when I was taking herbs for depression and anxiety. I am not taking herbs now and still feeling dizzy. Has anyone had any problem with Chinese herbs?

A. My mom had hyperthyroidism, but not with herbs. Until she told the exact things to the doctor, her treatment was difficult and once she revealed the medicine history to the doctor she was very well treated. Similarly I expect from you to tell your doctor about the herbs you are taking and you must tell this to your Chinese medicine practitioner as well. There are chances that you may have high level of thyroid and these herbs just boosted them or increased them as Chinese medicine do not have high side effects. Please open to your doctor during investigation and treatment.
