Sinus tachycardia, the most common
The palpitation and tachycardia are among the symptoms that often motivate medical consultation. However, usually more intense when accompanied by less serious organic disease.
Pounding heart is usually a less ominous symptom pain and Designs (difficulty breathing) and is very common. Unpleasant sensation consists of the action of the heart, whether fast or slow, regular or irregular. It is often less important disorders of cardiac rhythm: premature beats and paroxysmal atrial tachycardia, or heart action regular and strong, fast or slow, depending on exertion, excitement, toxins (snuff, caffeine, alcohol) or infection. Minor disorders palpitations occur more easily if the person is nervous or very sensitive. Less palpitations often occur due to a direct alteration of the heart.
Should be emphasized that palpitations and tachycardia often do not indicate primary physical disorder but mental disorder, are the most important symptoms of cardiac neurosis.
It is proven that when a person experiences or hyper nervous exhaustion often distorts their sense of values and criteria, especially in matters related to the physical and mental wellbeing. If at a stage of this kind the person lifts an object or ascending a slope, you may notice an immediate and rapid beating of the heart strong. This symptom usually disappears quickly, but if it is repeated, the person can be convinced that something serious is happening to your heart. The person’s nervous state produces introspection, anxiety and uncertainty sufficient to increase cardiac irritability and lower the threshold at which manifest palpitations, tachycardia and concomitant symptoms of cardiac neurosis.
A palpitation is a normal feeling when there is significant increase in strength and frequency of the heartbeat and the person concerned saying “hit the heart feels” or “beating too hard or too fast.” Light exercise in normal subjects alone can cause some difficulty in breathing. When the activity is stronger, it is easy to perceive this “pounding” of the heart against the chest. At rest, this feeling can hit persisting with something after the frequency has returned to normal, which proves that you can feel “heartbeat stronger” even though this is often not increased.
Persistent tachycardia palpitation not usually accompanied by continuous or at least not to the extent that one might expect. Patients with decompensated heart whose pulse rate exceeds 100 per minute, even during sleep, may have palpitations insignificant. Those suffering from chronic infections and tachycardia originate lasting fever often have no palpitation although the pulse is very fast.
The quick action of the heart is the most common cardiac manifestation and patent, which results in tachycardia and therefore is the first demonstration that is discovered in the medical consultation.
The heartbeat frequency is an expression of the power of rhythmicity (automatic) inherent in all parts of the heart, but it is more developed in those parts that make up the standard pacemaker.
Many physiological regulatory mechanisms can change the frequency of the heartbeat and classify them into chemical and nervous.
The chemical regulation of heart falls to some complex substances such as hormones. This regulation is slow. And nervous regulation is usually immediate, because the stimulus and the effect is short. Addition reaction involving the nervous system usually short and the effect disappears quickly ceases when the stimulus, whereas the effect of hormones tend to persist after stimulation ceased.
Variations and causes of tachycardia are many and have their classification. Just mention the most common is sinus tachycardia.
Sinus tachycardia is a sustained increase in heart rate that exceeds the normal limits of a person.
It is observed in many healthy people and is normal tendency in some families. Sinus tachycardia is experienced passing all subjects as physiological reaction to physical activity, food intake, emotions, pain and applying heat to the body. It occurs particularly easily when overused alcohol, coffee, snuff and stimulating this kind. Some infectious diseases can cause fever states have tachycardia. Also some drugs, including epinephrine, atropine and derivatives nitrite.
The symptoms that a person with sinus tachycardia vary from just over sign of increased heart rate to a syndrome that can impede normal activity.
The pounding is the most common symptom, but it may occur restlessness, agitation, apprehension, anxiety and chest discomfort or pain, as the threshold for nervous symptoms and reactivity of the person. Diagnosis always related to the triggering factor.
In summary, we can conclude that the palpitations are often an emotional or mental disorder and do not involve a heart compulsorily.
Increasing the strength and frequency of the heartbeat and can cause heart arrhythmias various palpitation.
Strictly speaking, the tachycardia is a sign, but it is often a symptom, because the person does not complain of feeling the heart beat (palpitations) but the frequency of contraction which excessive note.
Frequent or persistent tachycardia may result from metabolic or hormonal disorders, emotional disturbances, mental illness or central nervous system, infections and other abnormalities affecting the body as a whole and also direct heart disease.
Consequently, all of these disorders require careful study to determine the cause of the disease. This way you can take proper and logical treatment.
