Your Thoughts on Negative P Waves and PACs
Male, 46 years old I have a concern regarding the presence of negative P waves that appear prior to experiencing premature atrial contractions (PACs). After these PACs, I observe that the P waves revert to a standard shape. What could be the underlying reasons for this, and should it raise any alarms? Is this condition a cause for concern? When I encounter a PAC, I can feel it like a momentary pause in my breathing or a sensation of breathlessness. These occurrences mainly take place when I am at rest, whether I am sitting down or in a semi-reclined position. I notice the negative P wave sparingly; I haven't had numerous instances to document this, and the ectopic beats are relatively few—around 50 may occur in a single day. Thank you for your insights!

It's understandable to be concerned about noticing changes in your heart rhythm, particularly the presence of negative P waves and premature atrial contractions (PACs). Let's break down what this means and what steps you can take.
Key Points:
- Negative P Waves and PACs: Negative P waves often indicate changes in electrical conduction in the heart, and they can occur before PACs, which are extra heartbeats originating in the atria.
- Symptoms: Feelings of breathlessness or pauses can be related to PACs, especially when they occur more frequently, but these sensations can also occur due to anxiety or other factors.
- Monitoring: While PACs can be common and often benign, understanding your heart’s activity is crucial.
Explanation:
Negative P waves can appear in various situations, including changes in heart position or specific electrical impulses. PACs themselves are typically harmless, especially if they are infrequent and not associated with any underlying heart disease. It's good that you've noted their frequency and the sensations you feel.
The sensations of breathlessness you experience may vary in intensity, but generally, if PACs are not accompanied by other concerning symptoms (such as chest pain or significant palpitations), they are often not a cause for alarm.
Next Steps:
-
Monitor Symptoms Closely:
- Keep a detailed diary of your PACs, including when they occur, how long they last, and any associated symptoms like breathlessness or anxiety.
-
Lifestyle Adjustments:
- Ensure you are well-hydrated, manage stress through relaxation techniques like deep breathing or meditation, and limit caffeine or stimulants which might provoke PACs.
-
When to Seek Further Evaluation:
- If you notice an increase in episodes, start having other symptoms like dizziness, chest discomfort, fainting, or if the sensations worsen, it's important to seek further evaluation.
-
Regular Check-ups:
- Discuss your observations and concerns with a healthcare professional during a routine visit. They can evaluate your heart rhythm, possibly with an EKG or monitor, and provide reassurance or additional insights.
Remember, while it's normal to be concerned about your heart rhythm, PACs are common and often not indicative of serious heart issues in a healthy individual. Keeping track of your symptoms and making some lifestyle changes can greatly assist in managing your situation. If you have more questions or need clarification, feel free to ask!

Concerns About Carotid Artery Dissection
A month ago, I inadvertently applied significant pressure to my carotid artery using my fingers. It’s somewhat difficult to articulate my rationale; I was simply scratching my neck, felt the rhythm of my pulse, and acted on impulse, perhaps due to my tendencies associated with obsessive-compulsive disorder. Furthermore, I had just gone 48 hours without rest and had consumed alcohol, which likely exacerbated the situation. Now I’m wondering whether this action could have instantiated a dissection or if it could potentially lead to such a condition in the future. I am a 20-year-old male, standing at 6 feet 1 inch, in good physical health, and I do not take any medications.
Unusual Brown Mark Appeared on My Hand (26 Male)
I noticed an unusual brown mark on my right hand about three weeks ago. Initially, I didn't pay it much attention, but now that it has persisted, I’m growing concerned. To clarify, this mark does not stem from any previous bruises, cuts, or burns. I haven’t experienced any injuries or trauma to that hand which could explain its appearance. Overall, I consider myself to be in good health; I exercise occasionally and maintain an average diet. I’m not currently on any medications and can't recall being sick for a significant amount of time. The spot itself does not cause any discomfort—it doesn't itch or sting; it simply exists on my skin. Applying pressure or touching it does not elicit any sensations or changes. I attempted to capture its appearance in photos, both with and without flash, to provide a clearer view. I would appreciate any insights from professionals, as my online research hasn't yielded useful answers. While finding a general practitioner in the Netherlands is straightforward, I’m hesitant to seek an appointment for what may turn out to be a minor issue and waste either party's time.
Appearance of Small Lumps Beneath the Skin on Calves
I'm 18 years old and have noticed that small lumps sometimes appear across my legs, primarily concentrated on my calves. These bumps aren't firm, and I don't experience any sensation when I touch them. Additionally, when I move my legs, I seem to notice even more of these lumps. I also experience a similar sensation of bumpiness under the skin when I press on the subcutaneous fat around my triceps. While I'm not overly worried, as they don’t cause me any discomfort, I am curious about what might be causing these lumps to form.
Encounter with a Bat
A 47-year-old man recounted an unsettling incident involving a bat that found its way into his bedroom. After capturing the creature in a bag, he was bitten during the process. Although he checked for injuries and saw no visible wounds, he came across information indicating that some bites may not show external signs. He now wonders if there are potential risks he should be aware of following this incident.
Could this be a bat-related bite?
Apologies for the unclear photo, but it's the best I could manage. (18M) A few nights ago, I was out for about an hour wearing slippers, and when I returned, I discovered some strange red welts on my foot and ankle. There are four bumps altogether, two of which are in pairs as illustrated. I reside in the Seattle area. At the moment, I am not experiencing any discomfort, and I don’t specifically remember any contact with the ground, although it’s possible I might have overlooked something. Lately, I find myself feeling anxious about the risk of rabies due to this situation.
