Precordial activity refers to the movement of the chest wall when the heart beats.  When the heart beats it pushes against the rib cage and diaphragm in a certain way.  An experienced health care provider can often tell by palpating (touching) for the apex (pointed end) of the heart, whether there is enlargement, disease, damage, and to what extent.  Terms such as lifts, heaves, and thrills are used when notating location and duration of the movement.  An easy to understand example might be that the apex of the heart can be felt lower or more to the right in a patient with an enlarged heart, than one with a normal heart.  Precordial activity by itself isn't a term that means there is anything wrong.  All hearts have precordial activity.

The systolic pressure is defined as the peak pressure in the arteries during the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle). The mean arterial pressure and pulse pressure are other important quantities.

I have taken numerous cardiac classes and would like to help you, but I need more information. What do you mean "working off 60% of its power"? Did your specialist measure your MABP? If you'd like to give me more info so I can help you out you can e-mail me @ mary.edwards4543@my.sinclair.edu

A dysrhythmia can be many things, but is usually cardiac in nature. The actual medical terminology for dysrhythmia is: Abnormal, disordered, or disturbed rhythm. It usually is a "irregular" heartbeat, which a lot of people have, but can be more serious. Consult your Dr. for further questions, and exact meaning of "your dysrhythmia".

Without a clinical history on why an EKG was done and without other related cardiac risk factors,  I find it hard to interpret what an upside down t wave means.  It can be normal then again what does the EKG look it.  Is the upside t wave occurring on multiple leads and which ones.  How does the qrs look like.  What did the doctor say?  I would say this is pretty hard to accurately interpret without the above info.

Pace maker is one which can emit electrical impulses.{e.g., in heart, pacemaker is SA node(sinoatrial node)}.\nEctopic is one which is occuring outside of their normal site.\nPresence of ectopic pacemaker means there's a point which situated outside of normal site which can emit impulses.\n[e.g., some people have ectopic pacemakers in atrial wall or ventricle wall which also emit impulses like SA node] {which lead to ectopic beats of heart (extra and irregular beats) which can be seen in ECG/EKG}

sinus bradycardia means slow heart rate \nsinus arrythmia means heart is not beating in the normal rythym but the heart beat is still starting in the right place.\nMany people live wiht this for their whole lives and never even know they have it. Stress less.

If it is what I'm thinking it is, let me put it into simple words.\n\nImagine a heart. The electric waves that make it beat go down ( from the upper to the bottom side) and leftwards\n \nA rightward axis would mean that the elecrical waves take an alternate way, upper to bottom plus left to right\n\nThat doesn't mean much, for it may be caused by several conditions. This is a finding that can be interpreted only  with clinical examination of your husband.

Becuase \n\nProximal means nearer to the center (trunk of the body) or to the point of attachment to the body. If another reference point is given, such as the heart, the proximal point of another organ or extremity is the point closest to the heart -- central rather than peripheral.\n\nDistal refers to sites located away from the center or midline of the body. The hand is distal to the shoulder. The thumb is distal to the wrist\n\nIt has to do with the relation to the center of the body not a specific body part.  I hope that helps.

A palindrome is a word, phrase, number or other sequence of units (such as a strand of DNA) that has the property of reading the same in either direction (the adjustment of punctuation and spaces between words is generally permitted). The word "palindrome" comes from the Greek πάλιν (palin) "back" and δρóμος (dromos) "way, direction". Composing literature in palindromes is an example of constrained writing.
