PAPULAR CARDIOLOGISTS IN HEBBALA ECG interpretation: points to remember 1 ECG reports should be short and based on clinical information where possible. 2 Check that the patient’s name is on the ECG and that the paper speed and calibration markers are correct. 3 Measure or estimate the heart rate—3 large squares = 100/minute. 4 Establish the rhythm. Look for P waves (best seen in L2). Are the P waves followed by QRS complexes? Look for anomalously conducted or ectopic beats. 5 Measure the intervals: PR, QRS duration and QT interval (for the latter, consult tables, but normal is less than 50% of the RR interval). 6 If the QRS complex is wide (> 3 small squares) consider the possibilities: LBBB, RBBB, WPW or ventricular rhythm or beats. If the pattern is of LBBB, there is no need in most cases to attempt further interpretation. 7 Estimate the QRS axis. In LAD, L1 and aVF diverge and L2 is predominantly negative. In RAD, L1 and aVF converge, while L2 matters little. Indeterminate axis is diagnosed when all six frontal leads are (more or less) equiphasic. 8 Check whether the criteria for LAHB or LAFB have been met. 9 Look for pathological Q waves. In general these are longer than 0.04 seconds and are more than 25% of the size of the following R wave.
How sleeping less than 6 hours affects your health After being awake for almost 14-16 hours, our body demands sleep. Minimum sleeping time required for a healthy mind and body is 7-8 hours. Although, this duration varies according to age. Because generally speaking, where a child can sleep for 12-14 hours, grownups can sleep for not more than 9 hours. Sound sleep is very essential otherwise, it can be harmful for our health. Let’s see how sleeping for less than 6 hours affects our health. Headache, weight gain and poor vision: When you sleep for less than 6 hours a day, it can not only give you headache all the time but can lead to a poor vision also. And if continued for a long time, may hamper your eyesight. The lesser you sleep the more weight you gain. And after-effects of gaining weight could be even more hazardous. Memory loss, heart disease, infection: Sleeplessness can have an adverse effect on one’s memory too. A person may find it difficult to remember even simple things. Also, infections can take a longer time to heal because sleep is something that stabilises and balances everything that goes wrong while we are awake. If we don’t get proper sleep, the process of healing takes longer. Lack of sleep can also elevate blood pressure which ultimately affects the heart. Urine overproduction, stammering and accident: Sleeping slows down urinating process but when you are awake for longer hours, you might have to urinate more than usual. Lack of sleep can also make you stammer while speaking. If lack of sleep continues, you may not be able to communicate properly. When you do not have sound sleep, your mental condition would not be stable because of declining concentration. You can be accident prone if you drive in such a condition. These are just a few of the ill effects. Sleeping for less than 5 hours is far more dangerous than you can even think. From behavioural to mental to physical effects, it can harm you in many more ways, So, have a sound sleep to avoid complications in life.
This ordinarily consists of monitoring of  is suspected. heart rate and rhythm,  repeated measurement of systemic arterial pressure by cuff,  obtaining chest radiographs to detect heart failure,  repeated auscultation of the lung fields for pulmonary congestion,  measurement of urine flow,  examination of the skin and mucous membranes for evidence of the adequacy of perfusion, and
The use of invasive hemodynamic monitoring is based on the following principal factors: 1. Difficulty in interpreting clinical and radiographic findings of pulmonary congestion even after a thorough review of noninvasive studies such as an echo-cardiogram. 2. Need for identifying noncardiac causes of arterial hypotension, particularly hypovolemia. 3. Possible contribution of reduced ventricular compliance to impaired hemodynamics, requiring judicious adjustment of intravascular volume to optimize left ventricular filling pressure. 4. Difficulty in assessing the severity and sometimes even determining the presence of lesions such as mitral regurgitation and ventricular septal defect when the cardiac output or the systemic pressures are depressed. 5. Establishing a baseline of hemodynamic measurements and guiding therapy in patients with clinically apparent pulmonary edema or cardiogenic shock. 6. Underestimation of systemic arterial pressure by the cuff method in patients with intense vasoconstriction. The prognosis and the clinical status of patients with STEMI relate to both the cardiac output and the pulmonary artery wedge pressure. Patients
THE HYPERDYNAMIC STATE. MI with hyperdynamic state—that is, elevation of sinus rate, arterial pressure, and cardiac index, occurring singly or together in the presence of a normal or low left ventricular filling pressure—and if other causes of tachycardia such as fever, infection, and pericarditis can be excluded, treatment with beta blockers is indicated. Presumably, the increased heart rate and blood pressure are the result of inappropriate activation of the sympathetic nervous system, possibly secondary to augmented release of catecholamines, pain and anxiety, or some combination of these.
