Precordial leads and Electrocardiography

The specific diagnosis of cardiac abnormalities was detected by an electrocardiograph, which was invented in 1903. They were detected by the transmission of the electrical impulses that were going through the heart’s conductive type tissues. Electrical impulses were recorded on to this device, which was attached to a patient’s chest and limbs by the use of leads (or electrodes). There were 12 leads with the 6 limb by the use of the leads (V1,V2,V3, V4, V5, V6) are measuring the electrical activity happening on the vertical type of plane. The precordial leads and their input are what make the electrocardiograph possible. The percordial leads help out to determine the location and also the extent of the myocardial damage. The leads are placed in specific regions at different angles register the electrical cardiac type of activity of the chest, which is on the plane that is horizontal. The hear regions that are monitored for valuable information, regarding the functions of it.

This type of leads are located on to the anterior chest and are placed as follows: The V1 is located on the right internal boarder on the forth intercostaln space, The V2 is located at the left internal border on the forth intercostal space, V3 – is located in between the leads V2 and V4,The V4 is located at the left middavicular line at the 5th intercostal space, V5 – is located at the anterior to the left of the axillary line but at the level that is the same as the V4, The V6 is located at the left midaxilliary line but at the level which is the same asas V4 is on. The leads that a precordial leads are also monitoring the heart, which is based on their regions. The regions are as follows: V1 and V2 – These are called septal leads. The septum which is inter-ventricular better measured with leads, The leads that are V3 and also V4 are called anterior leads. The anterior or that called the front wall of the ventricle are located on the left side is better measured with the leads, The leads V5 and V6 are called the lateral precordial or left precordial type of leads.

Because of the specific angles used, different places of the heart can be analyzed through the particular sets of leads. Every differnt type of electrodes is monitored differently in order to be able to achieve the different areas being tested. The type of Leads II, III, and aVF are the interior leads which best capture the activity which is electrical to the interior side region of the heart. The aVL, VE, and VB lateral leads measure the activity of the electrical measurements of the lateral left side of the left wall of the left type of ventricle. The lateral and interior leads are between lead II and can also therefore be referred to as the intercialateral lead.

The electrocardiograph is continuously diagnosing patients through the use of precordial leads. Make sure to have proper placement of these precordial leads for a clear reading. Always be sure to check for a inverted or negative QRS complex in AVR. Make sure to analyze your right chest leads – V1 and also V2. This does reveal more than the other of the two contiguous leads. This is where you can check for Anterior and Posterial wall infractions, a Bundle Branch Block, or a “R” wave progression, ect. Always focus on the leads I and AVF when checking your axis. In their pressence Axis vectors are inaccurate. Be sure to check for the Bundle Branch Block. Also, when checking for signs of infarct, you must omit AVR. Acute types of Myocardial infarction cannot be identified positively through the pressence of the LBBB.

The EKG is a way of guiding one through the heart like a map with the physiological and anatomical terrains being part of the heart. This allows an in-depth type of assessment for various type of cardiovascular diseases or conditions that patients may have. It is very possible to diagnose precordial chest pain and many other types of heart problems that may exist with your patients. The electrocardiograph has come a long way since 1903 but is still doing it’s job to help out the medical community and it’s patients.

Causes, Symptoms and Treatments for precordial pain

What causes precordial pain?


Precordial Catch Syndrome refers to a sudden, sharp pain that is temporarily experienced at the left side of the chest near the nipple. It is a common type of chest pain that has been found to mainly occur in children and young adults. Precordial pain is less commonly experienced in adults. Another name for it is Texidor’s twinge, being named after one of the people who had first described this syndrome.

Precordial chest pain can be described as an intense, sharp pain that is sudden in onset, and short in duration. Pain arises on the left side of the chest nearly the nipple region. Unlike pain from a heart attack for example, precordial pain is fairly localized and does not tend to radiate. Precordial pain worsens with movement, when taking breaths in, and sometimes when breathing out as well. It may distract an individual from their normal activity, but only temporarily. Individuals who experience precordial pain tend to breathe shallowly to minimize the pain and wait for the pain to subside and resolve on its own.

precordial painThe intensity of pain that is experienced in individuals can vary. Some people may experience a dull persistent pain, while others might feel a highly intense and stabbing like pain in their chest. While the pain may be intense, it is temporary and short-lived.

Precordial pain is typically short and rapid in duration, and usually only lasts for about 30 seconds or less, up to 3 minutes. Rarely, the chest pain persists for a longer period of time than this. In some cases, a lingering ache may continue to be experienced after the initial pain goes away. Overall, precordial pain is quick to subside and resolves completely in individuals.

Episodes of precordial chest pain most often take place when a person is in an inactive state. Individuals may be sitting, lying down or are in a resting state when they experience a sudden onset of precordial chest pain. Chest pain can also occur in people following a sudden change in posture.

Precordial pain is believed to be the result of localized cramping of muscle tissue in the chest area, although the exact cause is not well understood. It has been suggested that the pain occurs due to the slight compression of a nerve and subsequent spasm of the intercostal muscle fibers found in the chest wall. Precordial catch syndrome has also been associated with stress and anxiety.

The frequency of precordial chest pain occurrences varies from individual to individual. In some people, precordial pain can be experienced a few times a day, daily, or infrequently over months or years. In most cases, experiences of chest pain associated with this syndrome are not very frequent.

Precordial catch syndrome is not considered to be a serious condition or a cause for concern. There is no need for treatment of precordial catch syndrome, nor is there any cure or treatment available for it. Precordial pain can be experienced in normal healthy individuals, and mostly occurs in young people, usually resolving by adulthood.
